   9 sysvinit (2.87dsf) world; urgency=low
  10
  11   * Fix typos and do minor updates in the manual pages.
  12   * Correct section of mountpoint(1).
  13   * Document -e and -t options for telinit in init(8).
  14   * Update address of FSF in the COPYRIGHT file.
  15   * Document in halt(8) that -n might not disable all syncing.
  16     Patch by Bill Nottingham and Fedora
  17   * Adjust output from "last -x".  In reboot lines, print endpoint
  18     of uptime too.  In shutdown lines print downtimes rather than
  19     the time between downs.  Fix typo in string compare in last.c.
  20     Patch by Thomas Hood.
  21   * Improve handling of IPv6 addresses in last.  Patch from Fedora.
  22   * Document last options in usage information, previously only
  23     mentioned in the manual page.
  24   * Add new option -F to last, to output full date string instead
  25     of the short form provided by default.  Patch from Olaf Dabrunz
  26     and SuSe.
  27   * Adjust build rules to make sure the installed binaries
  28     are stripped.
  29   * Increase the compiler warning level when building.
  30   * Fix utmp/wtmp updating on 64-bit platforms.  Patch by Bill
  31     Nottingham and Fedora.
  32   * Avoid unchecked return value from malloc() in utmpdump.
  33     Patch from Christian 'Dr. Disk' Hechelmann and Fedora.
  34   * Make sure to use execle and no execl when passing environment to
  35     the new process.  Patch from RedHat.
  36   * Correct init to make sure the waiting status is preserved across
  37     re-exec.  Patch from RedHat.
  38   * Correct init to avoid race condition when starting programs during
  39     boot.  Patch from SuSe.
  40   * Allow 'telinit u' in runlevels 0 and 6.  Patch from Thomas Hood.
  41   * Change install rules to make pidof an absolute symlink.  Patch from
  42     Thomas Hood.
  43   * Improve error message from init if fork() fail.  Patch found in Suse.
  44   * Add support for SE Linux capability handling.  Patch from Manoj
  45     Srivastava, adjusted to avoid aborting if SE policy was loaded in
  46     the initrd with patch from Bill Nottingham and Fedora.
  47   * Add -c option to pidof for only matching processes with the same
  48     process root.  Ignore -c when not running as root.  Patch from
  49     Thomas Woerner and Fedora.
  50   * Adjust init to terminate argv0 with one 0 rather than two so that
  51     process name can be one character longer.  Patch by Kir Kolyshkin.
  52   * Make sure bootlogd exit with non-error exit code when forking of
  53     the child successfully.
  54   * Add bootlogd option -s to make it possible to control the use of
  55     fdatasync().  Patch from Thomas Hood.
  56   * Add bootlogd option -c to tell it to create the log file if it does
  57     not exist.  Patch from Thomas Hood.
  58   * Let bootlogd also look at ttyB* devices to work on HPPA.  Patch
  59     from Thomas Hood.
  60   * Change init to use setenv() instead of putenv, make sure the PATH
  61     value is usable on re-exec.  Patch from Thomas Hood.
  62   * Add usleep in killall5 after killing processes, to force the kernel
  63     to reschedule.  Patch from SuSe.
  64   * Modify pidof to not print empty line if no pid was found.
  65   * Modify init and sulogin to fix emergency mode's tty, making sure ^C
  66     and ^Z work when booting with 'emergency' kernel option.  Patch from
  67     Samuel Thibault.
  68   * Modify init to allow some time for failed opens to resolve themselves.
  69     Patch from Bill Nottingham and Fedora.
  70   * Modify init to shut down IDE, SCSI and SATA disks properly.  Patches
  71     from Sebastian Reichelt, Werner Fink and SuSe.
  72   * Modify wall to use UT_LINESIZE from <utmp.h> instead of hardcoded
  73     string lengths.  Patch from SuSe.
  74   * Change wall to make halt include hostname in output.
  75   * Change killall to avoid killing init by mistake.  Patch from SuSe.
  76   * Change killall5 to use the exit value to report if it found any
  77     processes to kill.  Patch from Debian.
  78   * Add option -o opmitpid to killall5, to make it possible to skip
  79     some pids during shutdown.  Based on patch from Colin Watson and
  80     Ubuntu.
  81   * Add references between killall5 and pidof manual pages.  Patch from Debian.
  82   * Modify killall to work better with user space file system, by
  83     changing cwd to /proc when stopping and killing processes, and
  84     avoiding stat() when the value isn't used.  Also, lock process
  85     pages in memory to avoid paging when user processes are stopped.
  86     Patch from Debian and Goswin von Brederlow with changes by Kel
  87     Modderman.
  88   * Change shutdown to only accept flags -H and -P with the -h flag,
  89     and document this requirement in the manual page.
  90   * Change reboot/halt to work properly when used as a login shell.
  91     Patch by Dale R. Worley and Fedora.
  92   * Let sulogin fall back to the staticly linked /bin/sash if both roots
  93     shell and /bin/sh fail to execute.

  97 sysvinit (2.86) cistron; urgency=low
  98
  99   * Fixed up bootlogd to read /proc/cmdline. Also keep an internal
 100     linebuffer to process \r, \t and ^H. It is becoming useable.
 101   * Applied trivial OWL patches
 102   * Block signals in syslog(), since syslog() is not re-entrant
 103     (James Olin Oden <joden@malachi.lee.k12.nc.us>, redhat bug #97534)
 104   * Minor adjustements so that sysvinit compiles on the Hurd
 105   * killall5 now skips kernel threads
 106   * Inittab entries with both 'S' and other runlevels were broken.
 107     Fix by Bryan Kadzban <bryan@kadzban.is-a-geek.net>
 108   * Changed initreq.h to be more flexible and forwards-compatible.
 109   * You can now through /dev/initctl set environment variables in
 110     init that will be inherited by its children. For now, only
 111     variables prefixed with INIT_ can be set and the maximum is
 112     16 variables. There's also a length limit due to the size
 113     of struct init_request, so it should be safe from abuse.
 114   * Option -P and -H to shutdown set INIT_HALT=POWERDOWN and
 115     INIT_HALT=HALT as environment variables as described above
 116   * Add "mountpoint" utility.
 117   * Slightly better algorithm in killall5.c:pidof()
 118   * Added some patches from fedora-core (halt-usage, last -t,
 119     sulogin-message, user-console)

 123 sysvinit (2.85) cistron; urgency=low
 124
 125   * Add IPv6 support in last(1)
 126   * Sulogin: even if the root password is empty, ask for a password-
 127     otherwise there is no way to set a timeout.
 128   * Removed support for ioctl.save.
 129   * Turned of support for /etc/initrunlvl and /var/run/initrunlvl
 130   * Fixed warts in dowall.c ("Dmitry V. Levin" <ldv@altlinux.org>)
 131   * Fix init.c::spawn(). The "f" variable was used both as file descriptor
 132     and waitpid(2) return code.  In certain circumstances, this leads to
 133     TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).
 134   * Fix fd leak in sulogin (Dmitry V. Levin).
 135   * More error checking in all wait() calling code (Dmitry V. Levin).
 136   * Fix argv[] initialization in spawn() (Dmitry V. Levin).
 137   * Change strncpy to strncat in most places (Dmitry V. Levin).

 141 sysvinit (2.84) cistron; urgency=low
 142
 143   * Don't use /etc/initlvl interface for telinit; only use /dev/initctl,
 144     and give a clear error when that fails.
 145   * Add -i/--init command line flag to init - this tells init
 146     'behave as system init even if you're not PID#1'. Useful for
 147     testing in chroot/jail type environments.

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

 260     For backwards compatibility when you try to boot a 2.0.x kernel
 261     with a linux > 2.1.70 /dev/console device.
 262   * Change src/Makefile for non-debian systems (mainly, RedHat)
 263   * Try to create /dev/initctl if not present; check every time to see
 264     if the dev/ino of /dev/initctl has changed and re-open it. This should
 265     help devfs a bit.
 266   * Send SIGUSR1 to init at bootup to let it re-open /dev/initctl;
 267     again in support of devfs.

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

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

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

 562    runlevel into utmp file etc)

 577   hooked up an UPS to the Linux machine. The

 580
 581 2.4a 22-Apr-93
 582 - Fixed last to reckognize BSD style wtmp logging.
 583 - Changed init to write wtmp records that are
 584   SysV compliant but are also reckognized by the
 585   BSD last. Added a '+' option to the 'process'
 586   field of inittab, for getties that want to do
 587   their own utmp/wtmp housekeeping (kludge!).
 588 - Now accepts a runlevel on the command line,
 589   and reckognizes the 'auto' argument. (Sets the
 590   environment variable AUTOBOOT to YES)
 591
 592 2.2.3 24-Mar-93

 600 - Made wait()'s asynchronous
 601 - Changed whole thing to one big state machine
 602 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
 603 - Added a new type of 'action', called leave. This

 605   runlevel specified in it's runlevel field to a
 606   level that's not. Nice to bring down NFS and the like.
 607
 608 2.1 28-Jan-93
 609 - Fixed a bug with 'boot' and 'once'.
 610 - Check 'initdefault' for validity.
 611 - Reckognizes "single" as command line argument.
 612 - Retries execvp with 'sh -c exec ..' if command
 613   is a shell script. (shouldn't execvp do this?)

 615
 616 2.0 08-Dec-92
 617 - Rewrote the code totally, so started with a new

 621   run standalone for test purposes.
 622

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