1 [ Werner Fink ]
2 * Add option -w to the last command to display the full user and
3 domain names in the output. Patch from Petr Lautrbach.
4 * Add a manual page for utmpdump as this tool is sometimes
5 very useful even if not intended for normal use.
6 * Use paths.h macros for wall
7 * Change path "/etc/powerstatus" to "/var/run/powerstatus"
8 * Detected also removable block devices at halt/reboot to be able
9 to flush data and send them the ATA standby command. This should
10 avoid data loss on USB sticks and other removable block devices.
11 * Flush block devices on halt/reboot if not done by the kernel.
12 * Set SHELL to /bin/sh in the environmant of shutdown.
13 * Retry to write out shutdown messages if interrupted.
14 * pidof/killall5 - make omit pid list a dynamic one.
15 * pidof - provide '-n' to skip stat(2) syscall on network based FS.

70 * Improve handling of IPv6 addresses in last. Patch from Fedora.
71 * Document last options in usage information, previously only
72 mentioned in the manual page.

74 of the short form provided by default. Patch from Olaf Dabrunz
75 and SuSe.

97 process root. Ignore -c when not running as root. Patch from
98 Thomas Woerner and Fedora.
99 * Adjust init to terminate argv0 with one 0 rather than two so that
100 process name can be one character longer. Patch by Kir Kolyshkin.
101 * Make sure bootlogd exit with non-error exit code when forking of
102 the child successfully.
103 * Add bootlogd option -s to make it possible to control the use of

106 not exist. Patch from Thomas Hood.
107 * Let bootlogd also look at ttyB* devices to work on HPPA. Patch
108 from Thomas Hood.

122 string lengths. Patch from SuSe.
123 * Change wall to make halt include hostname in output.
124 * Change killall to avoid killing init by mistake. Patch from SuSe.
125 * Change killall5 to use the exit value to report if it found any
126 processes to kill. Patch from Debian.

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

148 * Fixed up bootlogd to read /proc/cmdline. Also keep an internal
149 linebuffer to process \r, \t and ^H. It is becoming useable.
150 * Applied trivial OWL patches
151 * Block signals in syslog(), since syslog() is not re-entrant
152 (James Olin Oden <joden@malachi.lee.k12.nc.us>, redhat bug #97534)
153 * Minor adjustements so that sysvinit compiles on the Hurd
154 * killall5 now skips kernel threads
155 * Inittab entries with both 'S' and other runlevels were broken.
156 Fix by Bryan Kadzban <bryan@kadzban.is-a-geek.net>
157 * Changed initreq.h to be more flexible and forwards-compatible.
158 * You can now through /dev/initctl set environment variables in
159 init that will be inherited by its children. For now, only
160 variables prefixed with INIT_ can be set and the maximum is
161 16 variables. There's also a length limit due to the size
162 of struct init_request, so it should be safe from abuse.
163 * Option -P and -H to shutdown set INIT_HALT=POWERDOWN and
164 INIT_HALT=HALT as environment variables as described above
165 * Add "mountpoint" utility.
166 * Slightly better algorithm in killall5.c:pidof()
167 * Added some patches from fedora-core (halt-usage, last -t,
168 sulogin-message, user-console)

179 * Fixed warts in dowall.c ("Dmitry V. Levin" <ldv@altlinux.org>)
180 * Fix init.c::spawn(). The "f" variable was used both as file descriptor
181 and waitpid(2) return code. In certain circumstances, this leads to
182 TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).

455 sysvinit (2.66-1) unstable; urgency=medium
456
457 * Skipped 2.65. A development 2.65 got out by accident and is apparently
458 being used..
459 * Also compiles and runs with GNU libc (and on the Alpha)
460 * Fixed dowall.c not to exit when getpwuid() fails and uid == 0.
461 * Fixed init panic'ing on empty lines in /etc/inittab
462 * Changed default PATH to include /usr/local/sbin
463 * Set /dev/console as controlling terminal for sysinit,bootwait,wait,powerwait
464 This allows using ^C to interrupt some parts of eg the boot process.
465 * Remove old symlink in /var/log/initlvl; let init check both
466 /var/log and /etc itself.

611 runlevel into utmp file etc)

613 - Updated all scripts. Examples are in two directories:
614 etc (normal) and etc-sysv (sysv style scripts).

622 SysVinit-2.4.tar.z.
623
624 2.4g 15-May-93

626 hooked up an UPS to the Linux machine. The
627 keyword for catching the TreeFingerSalute is
628 now "ctrlaltdel" instead of "power{wait,fail}".
629
630 2.4a 22-Apr-93
631 - Fixed last to reckognize BSD style wtmp logging.
632 - Changed init to write wtmp records that are
633 SysV compliant but are also reckognized by the
634 BSD last. Added a '+' option to the 'process'
635 field of inittab, for getties that want to do
636 their own utmp/wtmp housekeeping (kludge!).
637 - Now accepts a runlevel on the command line,
638 and reckognizes the 'auto' argument. (Sets the
639 environment variable AUTOBOOT to YES)
640
641 2.2.3 24-Mar-93
642 - Ripped out the 'leave' action. To difficult, and
643 unneeded.

647
648 2.2 02-Mar-93
649 - Made wait()'s asynchronous
650 - Changed whole thing to one big state machine
651 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
652 - Added a new type of 'action', called leave. This
653 process will be executed when the system goes from a
654 runlevel specified in it's runlevel field to a
655 level that's not. Nice to bring down NFS and the like.
656
657 2.1 28-Jan-93
658 - Fixed a bug with 'boot' and 'once'.
659 - Check 'initdefault' for validity.
660 - Reckognizes "single" as command line argument.
661 - Retries execvp with 'sh -c exec ..' if command
662 is a shell script. (shouldn't execvp do this?)

664
665 2.0 08-Dec-92
666 - Rewrote the code totally, so started with a new
667 version number.

670 run standalone for test purposes.
671
672 1.3, 05-Jul-92
673 - Got a 386, so installed Linux. Added 'soft' reboot
674 to be default under linux. Fixed some typos.
675
676 1.2, 16-Jun-92
677 - Bugreport from Michael Haardt ; removed deadlock
678 and added 'waitpid' instead of 'wait' for SYSV.
679
680 1.1, 30-Apr-92
681 - Read manual wrong: there is no 'action' field called
682 process, but all entries are of type process. Every
683 'process' get exec'ed by /bin/sh -c 'exec command'.
684 - Rapidly respawning processes are caught in the act.
685 - _SYSV support is really Linux support,
686 done by poe@daimi.aau.dk on 25-Mar-92.
687
688 1.0, 01-Feb-92
689 - Initial version, very primitive for the Minix
690 operating system. Required some mods. to the
691 kernel.
