   1 sysvinit (2.88dsf) UNRELEASED; urgency=low
   2
   3   * Revert change from Fedora/RedHat where the now obsolete command
   4     INIT_CMD_CHANGECONS was introduced.  Based on feedback and patch
   5     from Bill Nottingham.
   6   * Adjust makefile to make sure the install directories are created
   7     before files are copied into them.
   8   * Fix minor bug in optimizing of argument parsing.  Based on
   9     report from jakemus on freshmeat.
  10   * Add casts to get rid of compiler warning about signed/unsigned issues.

  14 sysvinit (2.87dsf) world; urgency=low
  15
  16   * Fix typos and do minor updates in the manual pages.
  17   * Correct section of mountpoint(1).
  18   * Document -e and -t options for telinit in init(8).
  19   * Update address of FSF in the COPYRIGHT file.
  20   * Document in halt(8) that -n might not disable all syncing.
  21     Patch by Bill Nottingham and Fedora
  22   * Adjust output from "last -x".  In reboot lines, print endpoint
  23     of uptime too.  In shutdown lines print downtimes rather than
  24     the time between downs.  Fix typo in string compare in last.c.
  25     Patch by Thomas Hood.
  26   * Improve handling of IPv6 addresses in last.  Patch from Fedora.
  27   * Document last options in usage information, previously only
  28     mentioned in the manual page.
  29   * Add new option -F to last, to output full date string instead
  30     of the short form provided by default.  Patch from Olaf Dabrunz
  31     and SuSe.
  32   * Adjust build rules to make sure the installed binaries
  33     are stripped.
  34   * Increase the compiler warning level when building.
  35   * Fix utmp/wtmp updating on 64-bit platforms.  Patch by Bill
  36     Nottingham and Fedora.
  37   * Avoid unchecked return value from malloc() in utmpdump.
  38     Patch from Christian 'Dr. Disk' Hechelmann and Fedora.
  39   * Make sure to use execle and no execl when passing environment to
  40     the new process.  Patch from RedHat.
  41   * Correct init to make sure the waiting status is preserved across
  42     re-exec.  Patch from RedHat.
  43   * Correct init to avoid race condition when starting programs during
  44     boot.  Patch from SuSe.
  45   * Allow 'telinit u' in runlevels 0 and 6.  Patch from Thomas Hood.
  46   * Change install rules to make pidof an absolute symlink.  Patch from
  47     Thomas Hood.
  48   * Improve error message from init if fork() fail.  Patch found in Suse.
  49   * Add support for SE Linux capability handling.  Patch from Manoj
  50     Srivastava, adjusted to avoid aborting if SE policy was loaded in
  51     the initrd with patch from Bill Nottingham and Fedora.
  52   * Add -c option to pidof for only matching processes with the same
  53     process root.  Ignore -c when not running as root.  Patch from
  54     Thomas Woerner and Fedora.
  55   * Adjust init to terminate argv0 with one 0 rather than two so that
  56     process name can be one character longer.  Patch by Kir Kolyshkin.
  57   * Make sure bootlogd exit with non-error exit code when forking of
  58     the child successfully.
  59   * Add bootlogd option -s to make it possible to control the use of
  60     fdatasync().  Patch from Thomas Hood.
  61   * Add bootlogd option -c to tell it to create the log file if it does
  62     not exist.  Patch from Thomas Hood.
  63   * Let bootlogd also look at ttyB* devices to work on HPPA.  Patch
  64     from Thomas Hood.
  65   * Change init to use setenv() instead of putenv, make sure the PATH
  66     value is usable on re-exec.  Patch from Thomas Hood.
  67   * Add usleep in killall5 after killing processes, to force the kernel
  68     to reschedule.  Patch from SuSe.
  69   * Modify pidof to not print empty line if no pid was found.
  70   * Modify init and sulogin to fix emergency mode's tty, making sure ^C
  71     and ^Z work when booting with 'emergency' kernel option.  Patch from
  72     Samuel Thibault.
  73   * Modify init to allow some time for failed opens to resolve themselves.
  74     Patch from Bill Nottingham and Fedora.
  75   * Modify init to shut down IDE, SCSI and SATA disks properly.  Patches
  76     from Sebastian Reichelt, Werner Fink and SuSe.
  77   * Modify wall to use UT_LINESIZE from <utmp.h> instead of hardcoded
  78     string lengths.  Patch from SuSe.
  79   * Change wall to make halt include hostname in output.
  80   * Change killall to avoid killing init by mistake.  Patch from SuSe.
  81   * Change killall5 to use the exit value to report if it found any
  82     processes to kill.  Patch from Debian.
  83   * Add option -o opmitpid to killall5, to make it possible to skip
  84     some pids during shutdown.  Based on patch from Colin Watson and
  85     Ubuntu.
  86   * Add references between killall5 and pidof manual pages.  Patch from Debian.
  87   * Modify killall to work better with user space file system, by
  88     changing cwd to /proc when stopping and killing processes, and
  89     avoiding stat() when the value isn't used.  Also, lock process
  90     pages in memory to avoid paging when user processes are stopped.
  91     Patch from Debian and Goswin von Brederlow with changes by Kel
  92     Modderman.
  93   * Change shutdown to only accept flags -H and -P with the -h flag,
  94     and document this requirement in the manual page.
  95   * Change reboot/halt to work properly when used as a login shell.
  96     Patch by Dale R. Worley and Fedora.
  97   * Let sulogin fall back to the staticly linked /bin/sash if both roots
  98     shell and /bin/sh fail to execute.

 102 sysvinit (2.86) cistron; urgency=low
 103
 104   * Fixed up bootlogd to read /proc/cmdline. Also keep an internal
 105     linebuffer to process \r, \t and ^H. It is becoming useable.
 106   * Applied trivial OWL patches
 107   * Block signals in syslog(), since syslog() is not re-entrant
 108     (James Olin Oden <joden@malachi.lee.k12.nc.us>, redhat bug #97534)
 109   * Minor adjustements so that sysvinit compiles on the Hurd
 110   * killall5 now skips kernel threads
 111   * Inittab entries with both 'S' and other runlevels were broken.
 112     Fix by Bryan Kadzban <bryan@kadzban.is-a-geek.net>
 113   * Changed initreq.h to be more flexible and forwards-compatible.
 114   * You can now through /dev/initctl set environment variables in
 115     init that will be inherited by its children. For now, only
 116     variables prefixed with INIT_ can be set and the maximum is
 117     16 variables. There's also a length limit due to the size
 118     of struct init_request, so it should be safe from abuse.
 119   * Option -P and -H to shutdown set INIT_HALT=POWERDOWN and
 120     INIT_HALT=HALT as environment variables as described above
 121   * Add "mountpoint" utility.
 122   * Slightly better algorithm in killall5.c:pidof()
 123   * Added some patches from fedora-core (halt-usage, last -t,
 124     sulogin-message, user-console)

 128 sysvinit (2.85) cistron; urgency=low
 129
 130   * Add IPv6 support in last(1)
 131   * Sulogin: even if the root password is empty, ask for a password-
 132     otherwise there is no way to set a timeout.
 133   * Removed support for ioctl.save.
 134   * Turned of support for /etc/initrunlvl and /var/run/initrunlvl
 135   * Fixed warts in dowall.c ("Dmitry V. Levin" <ldv@altlinux.org>)
 136   * Fix init.c::spawn(). The "f" variable was used both as file descriptor
 137     and waitpid(2) return code.  In certain circumstances, this leads to
 138     TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).
 139   * Fix fd leak in sulogin (Dmitry V. Levin).
 140   * More error checking in all wait() calling code (Dmitry V. Levin).
 141   * Fix argv[] initialization in spawn() (Dmitry V. Levin).
 142   * Change strncpy to strncat in most places (Dmitry V. Levin).

 146 sysvinit (2.84) cistron; urgency=low
 147
 148   * Don't use /etc/initlvl interface for telinit; only use /dev/initctl,
 149     and give a clear error when that fails.
 150   * Add -i/--init command line flag to init - this tells init
 151     'behave as system init even if you're not PID#1'. Useful for
 152     testing in chroot/jail type environments.

 159     virtual console when checking /etc/shutdown.allow
 160   * Fix race condition in waitpid() [Andrea Arcangeli]
 161   * Call closelog() after openlog()/syslog() since recent libc's
 162     keep the logging fd open and that is fd#0 aka stdin.

 267   * Change src/Makefile for non-debian systems (mainly, RedHat)
 268   * Try to create /dev/initctl if not present; check every time to see
 269     if the dev/ino of /dev/initctl has changed and re-open it. This should
 270     help devfs a bit.
 271   * Send SIGUSR1 to init at bootup to let it re-open /dev/initctl;
 272     again in support of devfs.

 313   * Should compile with glibc 1.99 :)
 314   * Change behaviour of reboot(1) and halt(1) so that the default when
 315     the runlevel can't be determined is to call shutdown.
 316   * Added re-exec patch from Al Viro (21 Feb 1998):
 317         'U' flag added to telinit. It forces init to re-exec itself
 318         (passing its state through exec, certainly).
 319         May be useful for smoother (heh) upgrades.
 320         24 Feb 1998, AV:
 321         did_boot made global and added to state - thanks, Miquel.

 413   * Skipped 2.65. A development 2.65 got out by accident and is apparently

 415   * Also compiles and runs with GNU libc (and on the Alpha)
 416   * Fixed dowall.c not to exit when getpwuid() fails and uid == 0.
 417   * Fixed init panic'ing on empty lines in /etc/inittab
 418   * Changed default PATH to include /usr/local/sbin
 419   * Set /dev/console as controlling terminal for sysinit,bootwait,wait,powerwait
 420     This allows using ^C to interrupt some parts of eg the boot process.
 421   * Remove old symlink in /var/log/initlvl; let init check both
 422     /var/log and /etc itself.

 564 - Modelled more after the "real" sysVinit
 565 - Lots of changes all over the place.

 567    runlevel into utmp file etc)

 582   hooked up an UPS to the Linux machine. The
 583   keyword for catching the TreeFingerSalute is
 584   now "ctrlaltdel" instead of "power{wait,fail}".
 585
 586 2.4a 22-Apr-93
 587 - Fixed last to reckognize BSD style wtmp logging.
 588 - Changed init to write wtmp records that are
 589   SysV compliant but are also reckognized by the
 590   BSD last. Added a '+' option to the 'process'
 591   field of inittab, for getties that want to do
 592   their own utmp/wtmp housekeeping (kludge!).
 593 - Now accepts a runlevel on the command line,
 594   and reckognizes the 'auto' argument. (Sets the
 595   environment variable AUTOBOOT to YES)
 596
 597 2.2.3 24-Mar-93
 598 - Ripped out the 'leave' action. To difficult, and
 599   unneeded.

 603
 604 2.2 02-Mar-93
 605 - Made wait()'s asynchronous
 606 - Changed whole thing to one big state machine
 607 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
 608 - Added a new type of 'action', called leave. This
 609   process will be executed when the system goes from a
 610   runlevel specified in it's runlevel field to a
 611   level that's not. Nice to bring down NFS and the like.
 612
 613 2.1 28-Jan-93
 614 - Fixed a bug with 'boot' and 'once'.
 615 - Check 'initdefault' for validity.
 616 - Reckognizes "single" as command line argument.
 617 - Retries execvp with 'sh -c exec ..' if command
 618   is a shell script. (shouldn't execvp do this?)
 619 - Added patches to use syslog if defined.
 620
 621 2.0 08-Dec-92
 622 - Rewrote the code totally, so started with a new

 626   run standalone for test purposes.
 627
 628 1.3, 05-Jul-92
 629 - Got a 386, so installed Linux. Added 'soft' reboot
 630   to be default under linux. Fixed some typos.
 631
 632 1.2, 16-Jun-92
 633 - Bugreport from Michael Haardt ; removed deadlock
 634   and added 'waitpid' instead of 'wait' for SYSV.
 635
 636 1.1, 30-Apr-92
 637 - Read manual wrong: there is no 'action' field called
 638   process, but all entries are of type process. Every
 639   'process' get exec'ed by /bin/sh -c 'exec command'.
 640 - Rapidly respawning processes are caught in the act.
 641 - _SYSV support is really Linux support,
 642   done by poe@daimi.aau.dk on 25-Mar-92.
 643
 644  1.0, 01-Feb-92
 645 - Initial version, very primitive for the Minix
 646   operating system. Required some mods. to the
 647   kernel.
