Changes between versions 0.4b34 and 0.4b35 (released ??????????????)
====================================================================

1.      Added a note in the dump man page saying that the default
        blocksize can be 32 if -d is used with a high density argument.
        Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
        for the patch.

2.      Fixed configure to correctly understand CPPFLAGS, CFLAGS,
        LDFLAGS environment variables. Thanks to Arcady Genkin
        <antipode@users.sourceforge.net> for reporting the bug.

3.      Make -e/-E options of dump accept an unlimited number of inodes
        to be excluded, rather than a hardcoded maximum. Thanks to 
        Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.

Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
====================================================================

1.      Fixed the INSTALL file to reflect the actual install paths.
        Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
        reporting the bug.

2.      Fixed the configure script to only check for headers presence
        instead of trying to compile them. This should fix issues
        with old build environments. Thanks to Kari Lempiainen 
        <kari@funky.pp.fi> for reporting the bug.

3.      Fixed restore to correctly ignore sockets when comparing
        a dump (as socket cannot be properly restored anyway). Thanks
        to Gunther Reiszig <gunther@mit.edu> for reporting the bug.

4.      Fixed restore to correctly access the archive file (-A argument)
        even when using a remote tape. Thanks to Fabrice Bellet 
        <fabrice@bellet.info> for reporting the bug.

5.      Fixed (again) handling of long (largefile) seeks in rmt.
        Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
        the bug.

6.      Fixed restore corner case when dealing with large block sizes
        dump is able to write now (-b 1024). Thanks to Fabrice Bellet
        <fabrice@bellet.info> for reporting the bug.

7.      Fixed a bug preventing dump to access a filesystem having 
        a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
        for reporting the bug.

8.      Made dump store dump dates using explicit timezones, fixing a
        problem with incremental dumps if the timezone is modified 
        between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
        the bug report and the patch.

9.      Fixed a bug encountered when dumping individual files (not full
        filesystems or directories) and dangling symbolic links happen
        to be in the list of files. For as far as dump is concerned,
        dangling symbolic links are allowed, and are dumped as is.
        Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
        bug and providing the fix.

10.     Fixed open and creation modes and permissions for QFA and
        table-of-contents files in dump and restore. Thanks to 
        Philippe Troin <phil@fifi.org> for the patch.

11.     Fixed the archive file descriptor handling enabling it to be 0.
        This can happen in some cases when shell redirections are used.
        Thanks to Philippe Troin <phil@fifi.org> for the patch.

12.     Delayed the opening of archive file until after suid had been
        dropped (fixing a possible security issue if dump is suid). 
        Thanks to Philippe Troin <phil@fifi.org> for the patch.

13.     Fixed the 'S' command handling in the rmt client part.
        Thanks to Philippe Troin <phil@fifi.org> for the patch.
        
14.     Modified the end-of-tape script handling to print out statistics
        (and stop the timer) before launching the eot script. Also, the eot
        script does not get run anymore when using -M (which makes sense) or
        when multiple tapes are listed on the command line 
        (-f tape0,tape1,tapen) (which also makes sense).
        Thanks to Philippe Troin <phil@fifi.org> for the patch.

15.     Relicensed dump/restore under the 'revised' BSD license, as per
        ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.

16.     Added LZO compression to dump. This new compression method has
        the advantage of being super fast, thus not killing tape streaming
        on slow machines. Thanks to Helmut Jarausch 
        <jarausch@igpm.rwth-aachen.de> for the patch and to 
        Markus Oberhumer <markus@oberhumer.com> for giving special permission
        to include his miniLZO project (GPL licensed) in dump/restore.

17.     Some small buffer overruns fixes in rmt. Thanks to Antonomasia
        <ant@notatla.demon.co.uk> for reporting the bugs.

18.     Added a special rmt version which can do encryption when writing
        to tape. Read examples/encrypted_rmt/README for details on
        how to enable and configure it. Thanks to Ken Lalonde
        <ken@globalremit.com> for the patch.

19.     Made dump work with 2.5 kernel end of tape early warning semantics.
        Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.

20.     Fixed a bug which caused dump -w|-W not to work anymore, because
        the fs_freq and fs_passno fields in /etc/mtab are always set
        to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for 
        reporting the bug.

Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
=======================================================================

1.      Added a note in the restore man page clarifying the question
        'set the permissions on the current directory ?' asked by
        restore at the end of treatment in -i and -x modes.

2.      Fixed the endianess issues when reading compressed tapes.
        Thanks to Dark Force <daq4th@users.sourceforge.net> for
        reporting this bug and providing test cases.

3.      Fixed the "ACL won't be dumped" warning message (which showed
        an extra, unrelated error message). Thanks to Dragan Krnic
        <dkrnic@lycos.com> for reporting this bug.

4.      Made dump look first into /etc/mtab, then into /etc/fstab 
        when searching for filesystem paths. Also fixed some problems
        caused by binding mounts or multiple block device mounts.
        Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
        <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
        Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
        and #160305, Sourceforge bugs #618699 and #679832).

5.      Made dump's -I option accept the value '0' meaning all the
        read errors will be ignored. This can be useful when running
        dump from unattended sessions (like cron jobs). Thanks to
        John I Wang <jiwang@users.sourceforge.net> for the suggestion.

6.      Fixed the output of dump to indicate 'blocks' instead of
        'tape blocks' in the various messages (blocks are always
        1 Kilobyte, tape blocks are 1 BK * '-b' argument), and 
        made it clearly print the current blocksize at the start of
        a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
        the suggestions.

7.      Made rmt understand long (largefiles) seeks.

8.      Fixed build with very old versions of libext2fs, where
        EXT2_FT_* constants were undefined.

9.      Made dump accept the dumpdates path on the command line
        (-D file option) instead of using only the hardcoded one.
        Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
        suggestion.

10.     Enabled rmt, LFS, readline, QFA options by default in
        ./configure. Updated the configure process (new versions
        of config.guess, config.sub etc).

Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
=======================================================================

1.      Changed dump to use fcntl(F_SETLK) style locking instead
        of flock() when locking the dumpdates file. With the old 
        locking scheme, a local user having read rights on the 
        dumpdates file could be able to do a Denial of Service attack
        on dump. In order to lock the dumpdates file with the new
        scheme, the user would need to have write access on the file.
        Thanks to Richard Johnson <Richard.Johnson3@ey.com> for 
        reporting the bug (originally a bugtraq post).

2.      Fixed interactive 'ls' which caused spurious errors warnings
        about 'undefined filetypes' detected. Thanks to Jorgen Ostling 
        <jorgen_ostling@users.sourceforge.net> for reporting this 
        bug.

3.      Fixed dump's estimate when dealing with sparse inodes.

4.      Modified dump to allow setting a blocksize bigger than 32kB
        (raised the limit to 1024kB), because newer hardware needs
        this for proper operation. Thanks to Dirk Traenapp
        <dtraenapp@users.sourceforge.net> for reporting this.

5.      Fixed a bug causing Dump to stop and report an error if an
        inode number in the exclude file was followed by some amount
        of whitespace. Thanks to Jeffrey Sofferin 
        <sofferin@users.sourceforge.net> for reporting this bug.

6.      Fixed a bug which caused restore, in some particular cases,
        to ask some 'scary' questions and leave a bunch of RSTTMP
        directories behind when restoring incremental tapes. Thanks
        to Philippe Troin <phil@fifi.org> for reporting this bug and
        providing the test cases.

7.      Changed the wording when inodes are excluded from dump:
        replaced 'Added inode 7 to exclude list' with
        'Excluding inode 7 (resize inode) from dump', as suggested
        by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.

Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
===================================================================

1.      Fixed rmt open flags transmission (GNU's symbolic syntax over
        rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
        <eros@lamel.bo.cnr.it> for reporting the bug.

Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
===================================================================

1.      Made dump print out the ext2 logical block number in case of a read
        error, which can be given as an argument to debugfs' ncheck command,
        in order to find out the affected inode. Added note about this 
        usage in dump's man page.

2.      Fixed a problem in restore when reading tapes written on big
        endian machines with very old versions of dump. The patch was
        contributed by George Helffrich <george@geology.bristol.ac.uk>.

3.      Fixed the tape length calculation when using large tapes
        and compression. Thanks to Georg Lippold 
        <g_lippold@sourceforge.net> for reporting the bug.

4.      Added a new set of examples in dump_on_cd_2 directory, based
        on dump_on_cd examples but somewhat enhanced, supporting DVD
        media, and localized in english and german. Thanks to
        Georg Lippold <g_lippold@sourceforge.net> for the new scripts.

5.      Made dump save 32 bit UID/GID. Internally, this was achieved
        by switching from the old BSD inode format to the new BSD 
        inode format, which means that the tape format was changed.
        However, since all restore versions out there should 
        transparently support both inode formats, the change should
        have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
        reporting the bug.

6.      Fixed a lot of warnings in the code shown when compiling
        with 'gcc -W'. Thanks to Matthias Andree 
        <matthias.andree@stud.uni-dortmund.de> for reporting this.

7.      Fixed a small markup bug in the dump man page. Thanks to
        Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
        patch.

8.      Rewrote entirely the man pages using the tmac.an macro
        package (Linux man page format) instead of the original BSD
        format. They should be now cleaner and easier to modify.

Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
==================================================================

1.      Fixed a problem in the rmt ioctl command, where ioctl's issued from
        non Linux clients were misinterpreted. The description of the problem
        (incompatible numbering in Linux mtio opcodes) is documented at
        ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
        Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
        providing an excellent, cross-platform replacement for rmt in his
        star package.

2.      Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
        which caused restore to fail when the inode maps were not entirely
        contained on the first volume (when using really small volumes or
        when dumping a huge number of inodes).

3.      Fixed a problem in dump, where files in subdirectories of directories 
        that have the nodump flag set (or being excluded with -e/-E) were 
        sometimes incorrectly dumped (instead of being excluded). The original
        fix is from David C Lawrence <tale@dd.org> in the FreeBSD version 
        of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
        Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and 
        help testing the patch.

4.      Added some example scripts from Gerd Bavendiek <bav@epost.de>
        which makes one able to pipe the output of dump, by the net, to
        a remote CD-burner server.

5.      Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt), 
        and use GNU's symbolic syntax over rmt instead of numerical values
        to assure multiple platform compatibility.

6.      Documented the -d option in restore.

7.      Added a -v (verbose) mode to dump. For now it just prints the number
        of the inode being dumped, but this could evolve in future versions
        to include interesting debugging output.

8.      Added a -o flag to restore, which automatically restores the current
        directory permissions in -i or -x mode, without asking the operator
        whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
        and Peter Samuel <peters@e-smith.com>.

Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
====================================================================

1.      Fixed a bug in the QFA feature which could have caused 
        a bad tape positionning on restore (causing extra delays in
        restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.

2.      Added a small note in the dump man page specifying that
        there should be no white space between the option letter and
        the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>

3.      Made restore work with older versions of the readline library,
        by checking in configure for several extended symbols. Restore
        can now be compiled with a readline as old as the 2.0 release
        (though it may be a good idea to upgrade it to a more recent
        version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
        reporting the build failures.

4.      Fixed a performance problem with the QFA file creation in
        dump, which made unnecessary seeks on the tape slowing down
        the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
        reporting this issue.

5.      Removed the inclusion of some kernel headers in the dump
        source, which prevented the compile in some kernel/glibc
        headers/architecture combination. Thanks to Bdale Garbee
        <bdale@gag.com> for reporting the bug.

6.      Added the appropriate error message when dump fails to
        open the output file for writing. Thanks to Amith Varghese
        <amithv@yahoo.com> for reporting this bug.

7.      Made restore able to understand large Solaris ufsdump tapes 
        (containing inodes bigger than 4194304). Sun have introduced
        an "extension" to the dump tape format when dealing with
        those inodes, which was uncorrectly handled by Linux restore.
        Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
        providing a test case.

8.      Added the -m parameter to dump which optimises the output for
        inodes having been changed but not modified since the last dump
        ('changed' and 'modified' have the meaning defined in stat(2)).
        For those inodes, dump will save only the metadata, instead of
        saving the entire inode contents. Inodes which are either 
        directories or have been modified since the last dump are saved
        in a regular way.  Uses of this flag must be consistent, meaning
        that either every dump in an incremental dump set have the flag,
        or no one has it.

Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
=======================================================================

1.      Fixed behaviour of dump when exceeding resource limits
        (SIGXFSZ treatment).

2.      Added the -L flag to restore to allow the user to specify a 
        maximal allowed number of miscompares when using restore
        with the -C option to check the backup.

3.      Detailed the manual entry for the -N option of restore.

4.      Added the -a flag to restore to make able doing unattended
        restores in -i or -x mode (automatically walks through the
        multiple dump volumes).

5.      Extended the QFA mode to work with local files and/or
        remote tapes and files. This way, restore can know in advance
        the tape number and the offset for the inodes to extract and 
        can minimize the extraction time by seeking directly to the 
        good tape/offset.

6.      Added the -A <archive> option to both dump and restore, 
        which makes dump to archive a dump table-of-contents in
        the specified file to be used by restore to determine
        whether a file is in the dump file that is being restored.
        (the archive file syntax is also compatible with the
        Solaris ufsdump generated one).

7.      Small fix in restore making it able to read some (broken ?)
        Solaris ufsdump tapes.

8.      Fixed dump to correctly recognise the root filesystem when using
        ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
        for reporting this bug.

9.      Added the -P <file> option to restore to create a
        Quick File Access file from an already made dump. Patch 
        contributed by Uwe Gohlke <uwe@ugsoft.de>.

10.     Made restore compile and run on Solaris, making it a 
        possible replacement for the standard ufsrestore. Port was
        contributed by Uwe Gohlke <uwe@ugsoft.de>.

Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
=====================================================================

1.      Added a set of backup scripts from Eugenio Diaz
        <getnito@yahoo.com> in the examples section. It features
        automatic (cron based) full and incremental dumping of
        several filesystems on a separate filesystem.

2.      Fixed a off-by-one miscalculation which disabled dumping
        a one letter subdirectory. Thanks to Chris Siebenmann 
        <cks@utcc.utoronto.ca> for reporting the bug.

3.      Fixed several restore bugs occuring when trying to
        restore some missing files on the tape. Thanks to Chris
        Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.

4.      Fixed --with-ldopts configure argument passing, installing from
        a separate object directory, makefile cleanups contributed
        by <splite@purdue.edu>.

5.      Fix a bug which could caused, in some conditions, the highest
        number inode of a filesystem, to not be dumped. Many thanks
        to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
        chase this bug.
        
Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
=======================================================================

1.      Added a mini howto from Patrick Walsh in the examples 
        directory.

2.      Minor man pages syntax corrections. Thanks to
        Chris Danis <screechco@home.com> for reporting the bugs.

3.      Added a script from David B. Peterson <dave@toppledwagon.com>
        to the examples section. It features dumping several
        filesystems to a remote tape drive upon ssh.

4.      Added a patch provided by Richard Jones <rich@annexia.org>
        which allows BRADEMAX (number of read errors tolerated by
        dump) to be adjusted using the -I option.

5.      Fixed a bug which disabled doing "restore -C -f -". Thanks
        to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
        patch.

6.      Add the -l option to restore to specify if, when doing a
        remote restore, the file used to access the backup is a
        regular file (the defaults being a tape drive). Restore needs
        to know this information when reading a remote compressed 
        dump. Previously, this information was autodetected, but
        the autodetection code fails (with ioctl: Inappropriate ioctl 
        for device) when using a non Linux remote box. Thanks to 
        many users and especially to Eros Albertazzi 
        <eros@lamel.bo.cnr.it> for reporting this.

7.      Found a workaroung for the dump deadlock problem (3 childs 
        stuck in pause(), father in read()). The workaround seems
        to work for me and several beta-testers. If it doesn't work
        for you, please report back.

8.      Updated the RPM spec file (BuildPrereq, URL etc).

Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
========================================================================

1.      Fixed the permissions of a newly created QFA file by dump.

2.      Cleaned up the source of dump (the external variables 
        definition was a complete mess, making possible to have
        objects overlap).

3.      Fixed restore to use the full tape volume path when doing
        a compare (since it changes the working directory to the
        filesystem being compared in the process).

4.      Added the -q option to dump which makes dump abort 
        whenever it needs operator attention. It should be
        easier to use dump in scripts with this option.

5.      Detect the use of incompatible options to dump and
        refuse them (like -a and -B options together).

6.      Added bzip2 compression to dump/restore (use option -j level 
        to select it). Note that you will need a restore version
        >= 0.4b24 in order to restore a bzip2 compressed dump.
        The same warning as for the zlib compression applies:
        the tape format of a bzip2 dump is not compatible with the
        original BSD tape format.

7.      Fixed a overflow problem in dump corrupting the dump when
        very large files were encountered. Thanks to Vladimir Nadvornik 
        for the bug report.

8.      Added a ioctl(BLKFLSBUF) in dump which should flush the
        kernel buffer/page cache before starting the dump, helping
        a bit those who use dump on mounted filesystems. Thanks to
        John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
        for this suggestion.

9.      Updated the RPM spec file following the RedHat changes 
        (dynamically linked binaries now in /usr/sbin etc).

10.     Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
        which enables restore to recognise multi volume compressed dumps
        done on CD. Included his scripts for dump (which pipe the dump
        output directly into cdrecord) and restore. There is now 
        possible to to backups to CD on the fly!

Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
===================================================================

1.      Fixed a buffer overflow in restore/tape.c. Patch provided by
        Marcus Meissner (Caldera International Security Dept.).

2.      Implement the Sun rmt extended protocol. Patch submitted
        by Ian Gordon <iangordon@users.sourceforge.net>.

3.      Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of 
        the linux kernel header. This ensures that dump always has the
        latest version of this file. Patch submitted by
        Andreas Dilger <adilger@turbolinux.com>.

4.      Report any filesystem present in either /etc/fstab with a 
        positive passno or /etc/dumpdates in dump -w output.
        Patch submitted by Andreas Dilger <adilger@turbolinux.com>.

5.      Fixed the looping problem in dump introduced in the 
        previous version.

6.      Changed the -B option of dump to limit the size of 
        _compressed_ output per volume if compression is on.
        Patch contributed by Helmut Jarausch 
        <jarausch@igpm.rwth-aachen.de>. Note however that, since
        it is impossible to predict the size of the compressed
        data before doing the compression, the -B limit is a bit
        conservative.

7.      Fixed a bug in reading the operator typed file/tape path for
        the next volume in restore.

8.      Implemented a "-F script" option to restore which permits the
        user to specify a script which will be launched at the
        beginning of each tape, useful for automatic programming of
        tape changers for example. See the restore man page for the
        script parameters and return codes.

9.      Small fix for the QFA routines provided by Uwe Gohlke 
        <uwe@ugsoft.de>, and some recommendations for QFA uses in
        the man pages.

10.     Fixed the multivolume restoring where making a mistake
        to the 'Mount next tape' prompt caused several blocks to
        be lost.

11.     Enhanced the -e option of dump to take as a parameter a
        comma separated list of inode numbers.

12.     Added the -E option to dump which specify a file containing
        inode numbers to exclude from the dump.

13.     Fixed the compressed multi-volume dump + restore.

Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
==================================================================

1.      Made dump report the number of blocks dumped per volume.
        Thanks to Kenneth Porter <shiva@well.com> for the suggestion.

2.      Fix a bug in dump where waiting too much at the 'change volumes'
        question caused the volume to be rewritten. Thanks to
        Graham Reed <greed@users.sourceforge.net> for reporting the
        bug and providing a patch.

3.      Added a compression option to dump, contributed by Jerry
        Peters <gapeters@worldnet.att.net>.

        WARNING: the compression works only on files/pipes and 
        drives supporting variable block size.

        WARNING2: tapes created using the compression feature are
        incompatible with the standard dump tape format, and a
        version of restore >= 0.4b22 will be needed for extraction.

4.      Fixed some compilation problems for glibc 2.2.2 and 64 bit 
        architectures. Thanks to Paul Slootman <paul@debian.org> for
        the patch and to Bdale Garbee <bdale@gag.com> for forwarding
        it upstream.

5.      Many cleanups (CPP defines, const char warnings, check of
        ext2fs COMPAT flags, time_t cleanups, added libext2 version
        in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.

6.      Made --prefix option work in configure. All the install path
        are now based on the configure parameters.

7.      Added the Quick File Access mode in dump/restore, contributed
        by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
        a file tape position for each inode, and this file is used by 
        restore (if called with parameter Q and the filename)
        to directly position the tape at the file restore is currently 
        working on.  This saves hours when restoring single files from
        large backups, saves the tapes and the drive's head. Use
        --enable-qfa option of configure to compile in the QFA support.

8.      Added the possibility to dump several files and directories
        in a single invocation of dump. Thanks to Uwe Gohlke 
        <uwe@ugsoft.de> for implementing this option.

9.      Fixed the dumping and restoring of files with holes
        (files ending with holes didn't get dumped or restored 
        correctly).

10.     Fixed a socket descriptor leak in dump, which leaved opened
        3 file descriptors per dump process (and there is one dump
        process per tape).

11.     Fixed dump large file system support, by explicit use of
        open64/lseek64/etc functions (explicit use needed because 
        e2fsprogs libraries don't behave well when compiled with 
        FILE_OFFSET_BITS=64).

Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
======================================================================

1.      Fixed some bugs in the dump -w|-W logic introduced by
        the previous version. Thanks to Andreas Dilger 
        <adilger@turbolinux.com> for his help on this one.

2.      Fixed again a compilation problem when using old e2fs
        headers (filesystem label related). Thanks to many users
        who reported this stupid error.

3.      Fixed a build problem on old lib5 based systems dealing with 
        _PATH_MNTTAB being undefined. Thanks to John Adams
        <johna@onevista.com> for reporting the bug.

4.      Improved the error detection in restore when creating
        the temporary files in TMPDIR. Now restore will corectly
        report a 'no space left on device' error instead of 
        strange errors which could imply an archive corruption.
        Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
        bgjenero <bgjenero@sympatico.ca> for reporting the bug.

5.      Added the throughput information in dump's progression
        messages.  Thanks to Andreas Dilger <adilger@turbolinux.com> 
        for the patch.

6.      Use libext2fs's inode scanning routines, which are particularly
        robust when dealing with errors (especially when having some
        bad blocks on the filesystem). Many thanks to Colin
        <colin@horizon.com> for reporting the bug, investigating
        the issues, finding a workaround, writing the patch and
        fully testing it... (of course, if this patch will break
        anything, he is to blame for :-)).

7.      Made dump and restore LFS aware. Dump can dump a filesystem
        containing large files, generate a large file on output and
        restore can restore them. This feature is not enabled by
        default, use --enable-largefile option of configure to enable
        it (you need to have a LFS aware glibc though). Thanks to
        Andrea Arcangeli <andrea@suse.de> for submitting the patch,
        and to Theodore T'so <tytso@valinux.com> for his always
        useful thoughts.

8.      Made dump ask upon a tape write error if it should rewrite
        the current volume (assume this is a bad tape) or if it should
        assume an end-of-tape condition (useful for tape drives which
        behaves badly at the end of the tape). Thanks to Andreas
        Dilger <adilger@turbolinux.com> for the suggestion.

Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
=======================================================================

1.      Fixed a small compilation problem due to a change
        in the definintion of the struct sigaction in
        glibc 2.0 / libc5. Thanks to Gunther Schlegel 
        <schlegel@riege.de> for reporting the bug and to
        Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
        a fix.

2.      Modified the label and uuid analysis in order to be 
        self-contained (independant of kernel/libc headers). This 
        should fix the compile with older kernel/libc headers and
        will preserve the functionality. Thanks to Bernhard Erdmann
        <bernhard.erdmann@gmx.de> for reporting the bug.

3.      The 'exclude inode' option, if applied to a directory
        inode, excludes now correctly all the leaves of this 
        directory. Thanks to John R. Dennison 
        <gerdesas@users.sourceforge.net> for reporting the bug.

4.      Fixed the '-e' option to disable the possibility
        to exclude the root inode (which causes the dumps to
        be unreadable by restore). Prevented array overflow
        when multiple -e options are used.

5.      Fixed dump to correctly interpret a filesystem argument
        which is a mountpoint and it is not an absolute path 
        (as specified in the fstab). Thanks to Bernhard R. Erdmann 
        <be@berdmann.de> for reporting the bug.

6.      Made dump able to backup files larger than 2 GB. Note that
        dump still doesn't cope with files larger than 4 GB.

7.      Restore the real uid and gid before invoking an external
        RSH program (big hole when dump or restore is suid root!).

8.      Get the values for the default tape device and the location
        of fstab file from the system headers. Thanks to
        Andreas Dilger <adilger@turbolinux.com> for the patch.

9.      Made dump -w|-W report all recognized filesystems 
        present in either /etc/fstab or /etc/dumpdates, and present
        the list in the same order as in fstab file. Thanks
        to Andreas Dilger <adilger@turbolinux.com> for the patch.

10.     Made dump's -a (automatic end of tape detection) the
        default. Specifying one of -B, -c, -d or -s options will
        override the EOM detection. Thanks to Andreas Dilger
        <adilger@turbolinux.com> for the patch.

11.     Save the ext2 filesystem label into the dump volume label.
        Specifying a volume label on the command line (-L option)
        will override this feature. Thanks to Andreas Dilger
        <adilger@turbolinux.com> for the patch.

Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
=====================================================================

1.      Fixed the signal handling in dump (which I broke in 0.4b17)
        which was causing several strange dump failures (dump
        hanged or segmentation faults etc). 

2.      Specified the default blocksize in the dump man page.

3.      Changed two info messages of restore to be written on stdout
        instead of stderr in order to leave stderr only for errors
        or warnings. Thanks to Stephen Atwell 
        <satwell@urbana.css.mot.com> for the suggestion.

4.      Corrected an off by one calculation which prevented
        dumping a directory having a 1 character name length.
        Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
        for reporting the bug.

5.      Reinforce dump in order to allow only level 0 and no
        -u option when dumping a subdirectory, and document 
        this in the man page. Thanks to Bernhard Erdmann 
        <bernhard.erdmann@gmx.de> for reporting the bug.

6.      Fixed a small harmless bug in restore which caused
        in some conditions hard links to be restored several
        times (therefore generation some warning messages).
        Thanks to Kenneth Porter <shiva@well.com> for
        reporting the bug.

7.      Updated the RPM spec file to the latest RedHat version,
        providing FHS packaging and other cosmetic changes.
        You will need RPM version >= 3.0.5 in order to build the RPM.

8.      Updated the configure script to check for libtermcap
        before checking for libreadline, because we need this
        library in order to compile the readline support.

9.      Made dump understand the LABEL= and UUID= notation
        both in /etc/fstab and on the command line. Note that
        you will need the /proc filesystem in order to use
        these notations. Thanks to Erik Troan <ewt@redhat.com> 
        for providing the patch.

Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
===================================================================

1.      Fixed a potential buffer overflow in restore. Thanks
        to Stan Bubrouski <satan@fastdial.net> for reporting 
        the bug.

2.      Fixed a readline-related bug which prevented
        'cat DUMPFILE | restore -i -f -' from working. Thanks
        to Charles Karney <karney@users.sourceforge.net>
        for the bug report.

3.      Changed a few "panic" into "exit", causing restore to
        be more stable against some attacks (like the last one
        reported on Bugtraq, although the last version of restore
        was not vulnerable - just dumped core). Thanks to
        Andreas Hasenack <andreas@conectiva.com.br> for reporting
        the bugs to me.

4.      Removed the suid-root bit on dump and restore in the
        default build (and generated RPMs). It should be safer
        now. Users who need the suid-root capabilities in order
        to make network backups should read first the man page
        of dump and enable the suid bit manually.

5.      Added -ltermcap to the compile parameters for restore
        when using readline support, in order to make the compile
        process work on some systems (SuSE ?). Thanks to 
        Patrik Schindler <poc@pocnet.net> for reporting the bug.

Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
====================================================================

1.      The -F script is called now *only* at the end of a tape,
        not at the end of the dump. Thanks to Christian Haul
        <haul@informatik.tu-darmstadt.de> for the bug report.

        Normally, the device name and the current volume number
        are passed on the command line of the script. However,
        if you want the old style script (with no arguments
        passed on the command line), you can enable it in
        configure with the --enable-oldstylefscript.

2.      Use posix signal handling to preserve dump functionality 
        with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
        the patch.

3.      Made the exit code of restore in case of a 'C'ompare
        command reflect the result of the compare. An exit status
        of 0 means the dump archive is correct, 1 means tape errors,
        2 means that some files were modified. Thanks to Kenneth Porter
        <shiva@well.com> for the suggestion.

4.      Made (finally) quotes work in interactive restore.

5.      Small fixes in order to allow dump to compile with a 
        really old e2fsprogs version. Thanks to Ian Zimmerman 
        <itz@speakeasy.org> for the bug report.

6.      Add GNU readline capabilities to interactive restore.
        Use configure's --enable-readline flag to enable this feature.
        Thanks to Patrik Schindler <poc@pocnet.net> for the
        suggestion.

7.      Do the compare on the fly in restore 'C' mode (this will
        allow not to exhaust the available /tmp space when 
        ccmparing large files). Thanks to Kenneth Porter
        <shiva@well.com> for the suggestion.

Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
====================================================================

1.      Fixed some several duplicate 'DUMP: DUMP:' in the
        output of dump.

2.      Corrected the estimation of blocks to dump. Note that
        this is still wrong for large directory inodes, due
        to the size of a BSD directory entry on the tape
        (estimation is based on the size of the ext2 directory,
        which is smaller because it doesn't contain the null
        character at the end).

3.      Made dump report the total number of MB written to
        tape at the end of run. Thanks to W. Reilly Cooley
        <wcooley@nakedape.cc> for the patch.

4.      Added the -X option to restore giving the possibility
        to read the names of the files to be extracted/listed 
        from a text file (in addition of the command line). 
        Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the 
        patch.

5.      Added the device name and the current volume number
        as arguments to the end of tape script (dump -F option).

6.      Made the multi-volume dump work again (after having 
        broken it in 0.4b15). 

Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
===================================================================

1.      Added a prompt command in interactive restore mode. Thanks
        to Andreas Dilger <adilger@home.com> for the patch.

2.      Fixed a buffer overflow problem in dump (caused by 
        not checking the size of the filesystem parameter). 
        Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
        reporting this on Bugtraq (and to several dump users
        who forwarded me his mail).

3.      Added the '-F script' option to dump in order to 
        launch a script at the end of each tape (to be used
        with a tape changer, or to notify the sysadmin by
        pager etc.).

4.      Fixed a bug in restore compare code caused by the changes 
        I made in 0.4b14.

5.      Fixed the treatment of options using the old BSD syntax
        in both dump and restore.

Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
=======================================================================

1.      Fixed a bug in dump which may have caused invalid deleted 
        directories to be dumped out if they were deleted after the
        mapping pass. This could occure on active filesystem and lead
        to heap corruption (causing dump malfunction in many possible ways).
        Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
        bug and submitting the patch.

2.      Fixed the handling of the filesystem parameter in dump. A
        '/mnt/disk' parameter caused the disk contents to be dumped,
        but a '/mnt/disk/' parameter caused the mountpoint directory
        to be dumped (generally an empty directory).

3.      Improved the output of dump in order to tell which directory
        it is currently dumping (when dumping a subtree).

4.      Added the '-e' exclude inode option to dump. Thanks to
        Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.

5.      Added a REPORTING-BUGS file in order to provide a guide
        on how to correctly report a bug in dump/restore.

6.      Fixed a restore problem when restoring a hard link to an inode
        having the immutable or append-only attribute set. Thanks to
        Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.

7.      Fixed a compatibility problem between dumps made on little
        endian machines (the format was correct) and big endian 
        machines (the format was incorrect). This fix break the
        compatibility with the older dumps made on big endian 
        machines (sparc, m86k, ppc etc). For the first time in
        linux dump's history (I believe), the dumps made by *BSD, 
        Linux/alpha, Linux/sparc and Linux/x86 are compatible, 
        so interchangeable. Thanks to Rob Cermak
        <cermak@ahab.rutgers.edu> for submitting the bug and
        helping me test the fix.

8.      Fixed the way dump reports the remaining percent/time, if
        the number of blocks actually dumped exceeds the estimated
        number of blocks. Thanks to Jean-Paul van der Jagt 
        <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.

Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
======================================================================

1.      Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
        <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.

2.      Removed the requirement to build the RPM as root from the
        spec file. Thanks to Christian Weisgerber 
        <naddy@mips.rhein-neckar.de> for submitting this.

3.      Fixed a bug in dump related to the 'filetype' feature of ext2fs,
        causing dump to block when dumping really huge filesystems.
        Many thanks to Patrik Schindler <poc@pocnet.net> for 
        helping me find this bug.

4.      Fixed the treatment for an interrupt signal when dump access
        the remote tape through RSH. Thanks to Christian Weisgerber
        <naddy@mips.rhein-neckar.de> for providing the patch.

5.      Fixed a bug which was causing dump/restore to display
        garbage characters instead of the remote host name.

Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
=====================================================================

1.      Small fix in the dump man page. Thanks to Thorsten Kukuk 
        <kukuk@suse.de> for submitting the patch.

2.      Fix for the exit code when using the size estimate option of
        dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
        submitting the patch.

3.      Handle EINTR in atomical reads/writes in dump, which was causing
        dump to fail on some systems. Thanks to Eric Jergensen
        <eric@dvns.com> for reporting the bug and submitting the patch.

4.      Handle more than 16 characters for the device names in dumpdates.
        (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
        tracking down the problem and proposing the solution.

5.      Fixed a bug in dump which prevented the creation of the
        dumpdates file when doing a 0-level dump without already
        having a dumpdates file. Thanks to Patrik Schindler 
        <poc@pocnet.net> for reporting the bug.

6.      Changed the way dump 'S' flag reports the size estimate
        from number of blocks into bytes (making it compatible
        with the Solaris version, and simplifying things for
        amanda users). Thanks to Jason L Tibbitts III 
        <tibbs@math.uh.edu> for reporting the bug.

7.      Fixed a compatibility problem in linux/alpha dump tape format.
        Now the linux/alpha dump are (again) compatible with the
        other dump formats. But this breaks compatibility with
        older dumps made on alpha. Thanks to Mike Tibor 
        <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.  

Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
======================================================================

1.      Added a '--enable-kerberos' to configure.

2.      Added a 'S' option to dump which determines the amount of space
        that is needed to perform the dump without actually doing it, similar
        to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
        <cermak@ahab.rutgers.edu>.

3.      Added a 'M' multi-volume option to dump and restore which enables
        dumping to multiple files (useful when dumping to an ext2
        partition to make several dump files in order to bypass the 2GB
        file size limitation). The 'f' argument is treated as a prefix and
        the output files will be named <prefix>001, <prefix>002 etc. With
        the 'M' flag, restore automatically selects the right file without
        asking to enter a new tape each time.

4.      Fixed a memory leak which was causing dump to grow very big
        (270MB when dumping a 10GB filesystem...). Thanks to Jason 
        Fearon <jasonf@netrider.org.au> for reporting the bug.

Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
======================================================================

1.      Make configure test if the system glob routines support 
        extended syntax (ALTDIRFUNC). If not, use the internal glob
        routines instead of system ones. Thanks to Bernhard Sadlowski 
        <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
        and helping me resolve this and other minor libc5 compiling
        glitches.

2.      Fix a problem when dumping a ext2fs with the 'filetype'
        feature enabled. Thanks to Patrick J. LoPresti 
        <patl@cag.lcs.mit.edu> for reporting the bug and to
        Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.

3.      Made the nodump flag work on directories. A directory which
        has the nodump flag gets never dumped, regardless of its
        contents.

4.      Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
        which allows dump on an active ext3 filesystem. However, this
        is a "quick and dirty" patch which enables backup of an ext3
        filesystem through the ext2 compatibility (by ignoring the
        NEEDS_RECOVERY bit). The journal file is not recognized and
        it is dumped (it should not). 

5.      Test the superblock compatibility flags when dumping, in order
        to be sure that we know how to deal with specific features.

Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
====================================================================

1.      Use lchown instead of chown, fixing a possible security problem 
        when restoring symlinks (a malicious user could use this
        to deliberately corrupt the ownership of important system files).
        Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
        this and providing the patch.

Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
====================================================================

1.      Put dump sources under CVS, added Id tags in all files so
        one can use 'ident' on binary files.

2.      Added the dump/restore version in the usage text so one can
        easily verify the version he is using.

3.      Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
        a va_start/va_end problem on linux-ppc (always call va_start
        va_end in pairs each time we use a vararg function).

4.      Added again the DT_* constants because old libc does not
        contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
        for submitting the bug report.

5.      Use ext2fs_llseek instead of llseek. With recent e2fsprogs
        this should enable dumping big (huge) filesystems.

6.      Added the RSH environment variable in order to be able to
        use a rsh replacement like ssh when doing remote backups (and
        bypass the security limitations of rcmd). Now you can do remote
        backups without being root (or making dump setuid root).

7.      Modified again the way dumpdates works. For incremental dumps,
        we need to read dumpdates even if we are not using 'u' option.
        Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
        this should work.

Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
===================================================================

1.      Removed the 'k' flag from the restore 'about' text if kerberos
        was not compiled in.

2.      Prototyped (f)setflags from e2fsprogs and corrected the calls
        to them (fsetflags takes a char*, setflags an open fd!).

3.      (f)setflags is called only if the flags aren't empty. If the
        file is a special file, a warning is printed, because changing
        flags implies opening the device. Normally, a special file
        should not have any flag... (Debian bug #29775, patch provided
        by Abhijit Dasgupta <abhijit@ans.net>).

4.      Made possible to dump a file system not mentioned in /etc/fstab.
        (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).

5.      Changed the default behaviour to not create dumpdates
        unless 'u' option is specified. Removed the old "debian-patch"
        which provided the same thing. (Debian bug #38136, #33818).

6.      Removed all those dump*announce, since they were getting old...

7.      Added warning messages if dumpdates does not exist and
        when an inferior level dump does not exist (except for a level 0
        dump).

8.      Debugged the glob calls in interactive mode: restore used a 
        dirent struct which was different from the /usr/include/dirent.h
        one (this used to work, is it a glibc2 change?), so none of the 
        compat glob (which used /usr/include/dirent.h) or the system glob 
        worked. Restore use now the system dirent (and the system 
        DT_* constants), which are compatible with BSD ones.

9.      Added a configure flag (--with-dumpdatespath) to specify
        the location of dumpdates file. By default, it is 
        /etc/dumpdates.

10.     Added the "AUTHOR" and "AVAILABILITY" sections and 
        included the current date/version in man pages.

11.     Corrected the estimation of remaining time when
        the operator doesn't change the tapes quickly enough. This
        was an old bug, I thought I corrected it, and discovered
        that in fact it was corrected in two different places, so
        the results canceled each other...

Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
===================================================================

1.      Integrated multiple patches from RedHat, Debian and SuSE:

        - tweak dump/itime.c to not try to read dumpdates if the 'u' option 
          isn't specified.
        - several fixes in the man pages.
        - update the default tape device to /dev/st0.
        - many updates for Linux Alpha (byte ordering, size_t etc).
        - buffer overruns.
        - use environment variable for TMPDIR (instead of /tmp).
        - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
        - workaround egcs bug (RedHat bugs #4281 and #2989).
        - wire $(OPT) throughout Makefile's.

2.      Upgrade the dump revision to 1, making possible to dump filesystems
        made with e2fsprogs-1.15 or newer. Nothing seems to break...

3.      Fix some compile warnings, prototype all functions.

4.      Use glibc err/glob instead of internal compatibility
        routines (only if available).

5.      Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
        by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).

Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
======================================================================

1.      Integrated the changes from FreeBSD-3.1-RELEASE
        (mostly bug fixes, buffer overruns, dump has now an "automatic
        tape length calculation" flag, dump/restore can use kerberos now
        (this is NOT tested), use environment variables for TAPE and
        RMT etc.).

2.      Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)

3.      Corrected a bug in restore when using 'C' option with multi-volumes
        tapes (files splited accros two tapes give "size changed" errors
        when comparing).

4.      Corrected the long standing bug when dumping multiple tapes.
        This works for me, needs further testing.

Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
====================================================================

1.      Dump now runs correctly on kernels 2.1.x
        Fix made by Gerald Peters <gapeters@worldnet.att.net>

Changes between versions 0.4b2 and 0.4b3
========================================

1.      Use realpath() if available

2.      Report statistics

Changes between versions 0.4b1 and 0.4b2
========================================

1.      Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
        the patch)

2.      Fixed restore to make it able to read FreeBSD 2.x dumps again

3.      Fixed configure.in to correctly handle --enable-rmt

Changes between versions 0.3 and 0.4b1
======================================

1.      Integrated the changes from 4.4BSD-Lite2

2.      Integrated the patches from Debian and Red Hat

3.      Portability changes: use the __u32, __u16, __s32, and __s16 types

4.      Changed dump to use the Ext2fs library to get block addresses.  This
        should solve the endianness problem on SparcLinux.

5.      Created a configure.in file (shamelessly stolen from the e2fsprogs
        distribution's one) to use autoconf

6.      Fixed a few minor bugs

Changes between versions 0.2e and 0.2f
======================================

1.      Added the creation of named pipes (fifos) in restore.

2.      Added the -N flag in the restore manual page.

3.      Added the file kernel.patch which contains the llseek() optimization
        patch for 1.2.x kernels.

4.      Fixed a bug in the restoration of symbolic links: owner and group were
        not restored.

5.      Integrated some changes from FreeBSD 2.2.

6.      Added a call to ftruncate() after restoring each file to restore
        correctly files ending by a hole.

Changes between versions 0.2d and 0.2e
======================================

1.      Fixed a bug in the "set owner/mode" process.  Every file was restored
        with owner = root (0) and group = root/wheel/whatever (0).

Changes between versions 0.2c and 0.2d
======================================

1.      Dump is now able to backup 2GB+ filesystems.

2.      Dump and restore can now be linked as static binaries.

Changes between versions 0.2b and 0.2c
======================================

1.      Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.

Changes between versions 0.2a and 0.2b
======================================

1.      Really fixed the bug that I should have corrected in 0.2a.

2.      Enabled optimization again.

Changes between versions 0.2 and 0.2a
=====================================

1.      Disabled the optimization during compilation.

Changes between versions 0.1 and 0.2
====================================

1.      Fixed a bug in fstab.c which caused a null pointer to be stored in
        the fs_type field (actually, I modified the file fstab.c to make it
        use the mntent functions).

2.      Dump and restore now use a 4.3 BSD compatible dump format.  Backups
        made by dump should be readable by the BSD restore and backups made
        by the BSD dump should be readable by restore.  Unfortunately, this
        means that the dump format has changed between version 0.1 and version
        0.2 :-(

3.      Dump is now able to backup a subtree, it is no longer limited to whole
        filesystems like the BSD version.

4.      Dump now uses ext2_llseek() so it is able to backup filesystems bigger
        than 2 GB.

Changes between versions 0.0 and 0.1
====================================

1.      Now create links rdump and rrestore during the `make install' step.

2.      Linux port specific bugs added to the manual pages

3.      Incorrect estimation of the number of tapes blocks fixed when doing
        incremental backups.

4.      Better ls-like format in restore in interactive mode.
