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.

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

72 of the short form provided by default. Patch from Olaf Dabrunz
73 and SuSe.

92 Srivastava, adjusted to avoid aborting if SE policy was loaded in
93 the initrd with patch from Bill Nottingham and Fedora.
94 * Add -c option to pidof for only matching processes with the same
95 process root. Ignore -c when not running as root. Patch from
96 Thomas Woerner and Fedora.
97 * Adjust init to terminate argv0 with one 0 rather than two so that
98 process name can be one character longer. Patch by Kir Kolyshkin.
99 * Make sure bootlogd exit with non-error exit code when forking of
100 the child successfully.
101 * Add bootlogd option -s to make it possible to control the use of
102 fdatasync(). Patch from Thomas Hood.

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

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

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

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

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

453 sysvinit (2.66-1) unstable; urgency=medium
454
455 * Skipped 2.65. A development 2.65 got out by accident and is apparently
456 being used..
457 * Also compiles and runs with GNU libc (and on the Alpha)
458 * Fixed dowall.c not to exit when getpwuid() fails and uid == 0.
459 * Fixed init panic'ing on empty lines in /etc/inittab
460 * Changed default PATH to include /usr/local/sbin
461 * Set /dev/console as controlling terminal for sysinit,bootwait,wait,powerwait
462 This allows using ^C to interrupt some parts of eg the boot process.
463 * Remove old symlink in /var/log/initlvl; let init check both
464 /var/log and /etc itself.

609 runlevel into utmp file etc)
610 - now using "reliable" signals instead of V7 style.
611 - Updated all scripts. Examples are in two directories:
612 etc (normal) and etc-sysv (sysv style scripts).

620 SysVinit-2.4.tar.z.
621
622 2.4g 15-May-93

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

645
646 2.2 02-Mar-93
647 - Made wait()'s asynchronous
648 - Changed whole thing to one big state machine
649 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
650 - Added a new type of 'action', called leave. This
651 process will be executed when the system goes from a
652 runlevel specified in it's runlevel field to a
653 level that's not. Nice to bring down NFS and the like.
654
655 2.1 28-Jan-93
656 - Fixed a bug with 'boot' and 'once'.
657 - Check 'initdefault' for validity.
658 - Reckognizes "single" as command line argument.
659 - Retries execvp with 'sh -c exec ..' if command
660 is a shell script. (shouldn't execvp do this?)

662
663 2.0 08-Dec-92
664 - Rewrote the code totally, so started with a new
665 version number.
666 - Dropped Minix support, this code now is Linux - specific.
667 - With TEST switch on, this init & telinit can
668 run standalone for test purposes.
669
670 1.3, 05-Jul-92
671 - Got a 386, so installed Linux. Added 'soft' reboot
672 to be default under linux. Fixed some typos.
673
674 1.2, 16-Jun-92
675 - Bugreport from Michael Haardt ; removed deadlock
676 and added 'waitpid' instead of 'wait' for SYSV.
677
678 1.1, 30-Apr-92
679 - Read manual wrong: there is no 'action' field called
680 process, but all entries are of type process. Every
681 'process' get exec'ed by /bin/sh -c 'exec command'.
682 - Rapidly respawning processes are caught in the act.
683 - _SYSV support is really Linux support,
684 done by poe@daimi.aau.dk on 25-Mar-92.
685
686 1.0, 01-Feb-92
687 - Initial version, very primitive for the Minix
688 operating system. Required some mods. to the
689 kernel.
