sysvinit (2.88dsf) world; urgency=low

  [ Petter Reinholdtsen ]
  * Mention new home on Savannah in README.
  * Revert change from Fedora/RedHat where the now obsolete command
    INIT_CMD_CHANGECONS was introduced.  Based on feedback and patch
    from Bill Nottingham.
  * Adjust makefile to make sure the install directories are created
    before files are copied into them.
  * Simplify build rules, based on patch from Mike Frysinger and Gentoo.
  * Fix minor bug in optimizing of argument parsing.  Based on
    report from jakemus on freshmeat.
  * Add casts to get rid of compiler warning about signed/unsigned issues.
  * Change tty handling in init to make sure the UTF-8 flag is not cleared
    on boot.  Patch from Samuel Thibault.
  * Add Makefile in toplevel directory.
  * Print usage information when shutdown is used by non-root user.
    Patch from Mike Frysinger and Gentoo.
  * Sync shutdown manual page and usage information.  Patch from Mike
    Frysinger and Gentoo.
  * Fix race condition in utmp writing.  Patch from Gil Kloepfer via
    Mike Frysinger and Gentoo.
  * Rewrite findtty() in bootlogd to recursively search /dev/ for the
    correct device, to handle terminal devices for example in /dev/pty/.
    Patch from Debian.
  * Make sure bootlogd findpty() returns an error value when it fails to
    find a usable pty.  Patch from Rob Leslie via Debian.
  * Make sure bootlogd fflush() every line, even if asked not to flush
    to disk using fdatasync().  Patch from Scott Gifford via Debian.
  * Add compatibility code to handle old path "/etc/powerstatus" for a
    while.
  * Incude definition for MNT_DETACH which is missing in older GNU libc
    headers.
  * Do not strip binaries before installing them, to make it easier to
    get binaries with debug information installed.

  [ Werner Fink ]
  * Add the comment from Andrea Arcangeli about the correct
    place of setting the default childhandler within spawn().
  * Make sure that newline is printed out for last(1) even
    if an utmp record entry is truncated.
  * Check if utmp not only exists but also is writable and delay
    writing out of the utmp runlevel record if utmp is not writable.
  * Be able to find libcrypt also on 64 bit based architectures.
  * Add option -w to the last command to display the full user and
    domain names in the output.  Patch from Petr Lautrbach.
  * Add a manual page for utmpdump as this tool is sometimes
    very useful even if not intended for normal use.
  * Use paths.h macros for wall
  * Change path "/etc/powerstatus" to "/var/run/powerstatus"
  * Detected also removable block devices at halt/reboot to be able
    to flush data and send them the ATA standby command.  This should
    avoid data loss on USB sticks and other removable block devices.
  * Flush block devices on halt/reboot if not done by the kernel.
  * Set SHELL to /bin/sh in the environmant of shutdown.
  * Retry to write out shutdown messages if interrupted.
  * pidof/killall5 - make omit pid list a dynamic one.
  * pidof - provide '-n' to skip stat(2) syscall on network based FS.
  * init - avoid compiler warnings
  * init - initialize console by using the macros from ttydefaults.h
  * init - add the possiblity to ignore further interrupts from keyboard
  * init - add the possiblity to set sane terminal line settings
  * sulogin - add the possibility to reset the terminal io
  * Fix some minor problems
  * init - enable is_selinux_enabled() to detect selinuxfs
  * Add fix for Debian bug #536574 -- Can be enabled by -DACCTON_OFF
  * Add helper program fstab-decode to make it easier to handle
    /etc/mtab content. Patch by Miloslav Trmac and Fedora.
  * Add fix for Debian bug #335023 - Make sure TERM is set on FreeBSD.
  * Add fix for Debian bug #374038 - Make it clear that shutdown -c can
    only cancel a waiting shutdown, not an active one.
  * Add note to pidof manual page about the use of readlink(2). Patch by
    Bill Nottingham and Fedora.
  * Add PAM patch contrib/notify-pam-dead.patch based on Debian bug
    #68621, which will add PAM support for programs spawned by init on
    the console like sulogin. Based on patch by Topi Miettinen.  This
    patch is not applied by default yet while we review its
    usefullness.  It is only helpful for session handling, as sulogin
    do not use and will not use a PAM conv() function.  The current
    sulogin is able to handle DES as well as MD5, SHA, and Blowfish
    encrypted passwords due using getpwnam(3).
  * Move utmp/wtmp before the execvp() in spawn() to be sure to
    use the correct pid even on a controlling tty
  * Remaining problem is that the pid of the second fork() for
    getting a controlling tty isn't that reported by spawn()
  * Re-enable writting utmp/wtmp for boot scripts
  * Extend sulogin to support additional encryption algorithms
  * Re-enable maintenance message of sulogin
  * Enable the sulogin fallback password check to handle  MD5, SHA, and
    Blowfish encrypted passwords in case of getpwnam(3) fails.
  * sulogin picking the SELinux context was broken. Patch by Daniel Walsh

    the time between downs.  Fix typo in string compare in last.c.
    Patch by Thomas Hood.
  * Improve handling of IPv6 addresses in last.  Patch from Fedora.
  * Document last options in usage information, previously only
    mentioned in the manual page.

    the initrd with patch from Bill Nottingham and Fedora.
  * Add -c option to pidof for only matching processes with the same
    process root.  Ignore -c when not running as root.  Patch from
    Thomas Woerner and Fedora.
  * Adjust init to terminate argv0 with one 0 rather than two so that
    process name can be one character longer.  Patch by Kir Kolyshkin.
  * Make sure bootlogd exit with non-error exit code when forking of
    the child successfully.
  * Add bootlogd option -s to make it possible to control the use of

    some pids during shutdown.  Based on patch from Colin Watson and
    Ubuntu.
  * Add references between killall5 and pidof manual pages.  Patch from Debian.
  * Modify killall to work better with user space file system, by
    changing cwd to /proc when stopping and killing processes, and
    avoiding stat() when the value isn't used.  Also, lock process
    pages in memory to avoid paging when user processes are stopped.
    Patch from Debian and Goswin von Brederlow with changes by Kel
    Modderman.
  * Change shutdown to only accept flags -H and -P with the -h flag,
    and document this requirement in the manual page.

sysvinit (2.86) cistron; urgency=low

  * Fixed up bootlogd to read /proc/cmdline. Also keep an internal
    linebuffer to process \r, \t and ^H. It is becoming useable.
  * Applied trivial OWL patches
  * Block signals in syslog(), since syslog() is not re-entrant
    (James Olin Oden <joden@malachi.lee.k12.nc.us>, redhat bug #97534)
  * Minor adjustements so that sysvinit compiles on the Hurd 
  * killall5 now skips kernel threads
  * Inittab entries with both 'S' and other runlevels were broken.
    Fix by Bryan Kadzban <bryan@kadzban.is-a-geek.net>
  * Changed initreq.h to be more flexible and forwards-compatible.
  * You can now through /dev/initctl set environment variables in
    init that will be inherited by its children. For now, only
    variables prefixed with INIT_ can be set and the maximum is
    16 variables. There's also a length limit due to the size
    of struct init_request, so it should be safe from abuse.
  * Option -P and -H to shutdown set INIT_HALT=POWERDOWN and
    INIT_HALT=HALT as environment variables as described above
  * Add "mountpoint" utility.
  * Slightly better algorithm in killall5.c:pidof()
  * Added some patches from fedora-core (halt-usage, last -t,
    sulogin-message, user-console)

 -- Miquel van Smoorenburg <miquels@cistron.nl>  Fri, 30 Jul 2004 14:14:58 +0200

sysvinit (2.85) cistron; urgency=low

  * Add IPv6 support in last(1)
  * Sulogin: even if the root password is empty, ask for a password-
    otherwise there is no way to set a timeout.
  * Removed support for ioctl.save.
  * Turned of support for /etc/initrunlvl and /var/run/initrunlvl
  * Fixed warts in dowall.c ("Dmitry V. Levin" <ldv@altlinux.org>)
  * Fix init.c::spawn(). The "f" variable was used both as file descriptor
    and waitpid(2) return code.  In certain circumstances, this leads to
    TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).
  * Fix fd leak in sulogin (Dmitry V. Levin).
  * More error checking in all wait() calling code (Dmitry V. Levin).
  * Fix argv[] initialization in spawn() (Dmitry V. Levin).
  * Change strncpy to strncat in most places (Dmitry V. Levin).

 -- Miquel van Smoorenburg <miquels@cistron.nl>  Tue, 15 Apr 2003 16:37:57 +0200

sysvinit (2.84) cistron; urgency=low

  * Don't use /etc/initlvl interface for telinit; only use /dev/initctl,
    and give a clear error when that fails.
  * Add -i/--init command line flag to init - this tells init
    'behave as system init even if you're not PID#1'. Useful for
    testing in chroot/jail type environments.

 -- Miquel van Smoorenburg <miquels@cistron.nl>  Tue, 27 Nov 2001 13:10:08 +0100

  * Fix bug in shutdown where it didn't check correctly for a
    virtual console when checking /etc/shutdown.allow
  * Fix race condition in waitpid() [Andrea Arcangeli]
  * Call closelog() after openlog()/syslog() since recent libc's
    keep the logging fd open and that is fd#0 aka stdin.

 -- Miquel van Smoorenburg <miquels@cistron.nl>  Tue,  3 Nov 1998 11:09:13 +0100

sysvinit (2.75-4) unstable; urgency=low

  * Change sulogin password buffer to 128 characters.
  * Don't print control characters in dowall.c
  * Try to open getenv ("CONSOLE"), /dev/console and /dev/tty0 in order.
    For backwards compatibility when you try to boot a 2.0.x kernel
    with a linux > 2.1.70 /dev/console device.
  * Change src/Makefile for non-debian systems (mainly, RedHat)
  * Try to create /dev/initctl if not present; check every time to see
    if the dev/ino of /dev/initctl has changed and re-open it. This should
    help devfs a bit.
  * Send SIGUSR1 to init at bootup to let it re-open /dev/initctl;
    again in support of devfs.
  * Moved pidof to /bin (it's only a link to killall5 anyway)

  * Rewrote last.c to be much more memory friendly and correct,
    thanks to Nick Andrew <nick@zeta.org.au> and
    David Parrish <dparrish@zeta.org.au>

sysvinit (2.74-4) frozen unstable; urgency=medium

  * Add -o option to last to process libc5 utmp files.
  * Buffer overflow fixed in init.c (not very serious; only exploitable
    by root). Thanks to Chris Evans <chris@ferret.lmh.ox.ac.uk>

 -- Miquel van Smoorenburg <miquels@cistron.nl>  Wed, 15 Apr 1998 17:04:33 +0200

sysvinit (2.74-1) unstable; urgency=low

  * Should compile with glibc 1.99 :)
  * Change behaviour of reboot(1) and halt(1) so that the default when
    the runlevel can't be determined is to call shutdown.
  * Added re-exec patch from Al Viro (21 Feb 1998):
        'U' flag added to telinit. It forces init to re-exec itself
        (passing its state through exec, certainly).
        May be useful for smoother (heh) upgrades.
        24 Feb 1998, AV:
        did_boot made global and added to state - thanks, Miquel.
        Yet another file descriptors leak - close state pipe if
        re_exec fails.

sysvinit (2.73-1) unstable; urgency=low

  * Use siginterrupt, now that system calls are restarted by default.
    Main symptom was that the sulogin timeout didn't work but there
    might have been more hidden problems.
  * Kill process immidiately if turned off in inittab
  * Fixed sulogin check on tty arg.
  * Use strerror() instead of sys_errlist
  * wall now supports a '-n' option to suppress [most of] the banner.
    Debian doesn't use sysvinit's wall, but apparently Redhat does.
  * Add '-F' (forcefsck) option to shutdown
  * Close and reopen /dev/initctl on SIGUSR1 (mainly for a /dev in ram)

    daemons
  * Puts copyright file in the right place

 -- Miquel van Smoorenburg <miquels@cistron.nl>  Fri, 15 Nov 1996 12:23:33 +0100

sysvinit (2.66-1) unstable; urgency=medium

  * Skipped 2.65. A development 2.65 got out by accident and is apparently
    being used..
  * Also compiles and runs with GNU libc (and on the Alpha)
  * Fixed dowall.c not to exit when getpwuid() fails and uid == 0.
  * Fixed init panic'ing on empty lines in /etc/inittab
  * Changed default PATH to include /usr/local/sbin
  * Set /dev/console as controlling terminal for sysinit,bootwait,wait,powerwait
    This allows using ^C to interrupt some parts of eg the boot process.
  * Remove old symlink in /var/log/initlvl; let init check both
    /var/log and /etc itself.

2.50  14-Feb-1994

  SysVinit-2.4.tar.z.

2.4g 15-May-93

  now "ctrlaltdel" instead of "power{wait,fail}".

2.4a 22-Apr-93
- Fixed last to reckognize BSD style wtmp logging.
- Changed init to write wtmp records that are
  SysV compliant but are also reckognized by the
  BSD last. Added a '+' option to the 'process'
  field of inittab, for getties that want to do
  their own utmp/wtmp housekeeping (kludge!).

  and reckognizes the 'auto' argument. (Sets the
  environment variable AUTOBOOT to YES)

  unneeded.

2.2 02-Mar-93
- Made wait()'s asynchronous
- Changed whole thing to one big state machine
- Now using 'pseudo levels' # & * for SYSINIT & BOOT
- Added a new type of 'action', called leave. This
  process will be executed when the system goes from a
  runlevel specified in it's runlevel field to a 
  level that's not. Nice to bring down NFS and the like.

2.1 28-Jan-93
- Fixed a bug with 'boot' and 'once'.
- Check 'initdefault' for validity.
- Reckognizes "single" as command line argument.
- Retries execvp with 'sh -c exec ..' if command
  is a shell script. (shouldn't execvp do this?)
- Added patches to use syslog if defined.

2.0 08-Dec-92
- Rewrote the code totally, so started with a new
  version number.
- Dropped Minix support, this code now is Linux - specific.
- With TEST switch on, this init & telinit can
  run standalone for test purposes.

1.3, 05-Jul-92
- Got a 386, so installed Linux. Added 'soft' reboot
  to be default under linux. Fixed some typos.

1.2, 16-Jun-92
- Bugreport from Michael Haardt ; removed deadlock
  and added 'waitpid' instead of 'wait' for SYSV.

1.1, 30-Apr-92
- Read manual wrong: there is no 'action' field called
  process, but all entries are of type process. Every
  'process' get exec'ed by /bin/sh -c 'exec command'.
- Rapidly respawning processes are caught in the act.
- _SYSV support is really Linux support,
  done by poe@daimi.aau.dk on 25-Mar-92.

 1.0, 01-Feb-92
- Initial version, very primitive for the Minix
  operating system. Required some mods. to the
  kernel.
