-Changes between versions 0.4b7 and 0.4b8 (released ???????????????)
+Changes between versions 0.4b24 and 0.4b25 (released ??????????????????)
+========================================================================
+
+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.
+
+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.
contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
for submitting the bug report.
-5. Added the RSH environment variable in order to be able to
+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.
