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.

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.
16 * init - avoid compiler warnings
17 * init - initialize console by using the macros from ttydefaults.h
18 * init - add the possiblity to ignore further interrupts from keyboard
19 * init - add the possiblity to set sane terminal line settings

75 * Improve handling of IPv6 addresses in last. Patch from Fedora.
76 * Document last options in usage information, previously only
77 mentioned in the manual page.

79 of the short form provided by default. Patch from Olaf Dabrunz
80 and SuSe.
81 * Adjust build rules to make sure the installed binaries
82 are stripped.
83 * Increase the compiler warning level when building.

102 process root. Ignore -c when not running as root. Patch from
103 Thomas Woerner and Fedora.
104 * Adjust init to terminate argv0 with one 0 rather than two so that
105 process name can be one character longer. Patch by Kir Kolyshkin.
106 * Make sure bootlogd exit with non-error exit code when forking of
107 the child successfully.

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

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

179 * Add IPv6 support in last(1)
180 * Sulogin: even if the root password is empty, ask for a password-
181 otherwise there is no way to set a timeout.
182 * Removed support for ioctl.save.
183 * Turned of support for /etc/initrunlvl and /var/run/initrunlvl
184 * Fixed warts in dowall.c ("Dmitry V. Levin" <ldv@altlinux.org>)
185 * Fix init.c::spawn(). The "f" variable was used both as file descriptor
186 and waitpid(2) return code. In certain circumstances, this leads to
187 TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).

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

614 - Lots of changes all over the place.
615 (like showing runlevel in "ps" listing, logging
616 runlevel into utmp file etc)
617 - now using "reliable" signals instead of V7 style.
618 - Updated all scripts. Examples are in two directories:
619 etc (normal) and etc-sysv (sysv style scripts).

621 - added support for serial console.
622 - updated Propaganda, manpages.
623 - added shutdown access control.
624

627 SysVinit-2.4.tar.z.
628
629 2.4g 15-May-93

631 hooked up an UPS to the Linux machine. The
632 keyword for catching the TreeFingerSalute is
633 now "ctrlaltdel" instead of "power{wait,fail}".
634
635 2.4a 22-Apr-93
636 - Fixed last to reckognize BSD style wtmp logging.
637 - Changed init to write wtmp records that are
638 SysV compliant but are also reckognized by the
639 BSD last. Added a '+' option to the 'process'
640 field of inittab, for getties that want to do
641 their own utmp/wtmp housekeeping (kludge!).
642 - Now accepts a runlevel on the command line,
643 and reckognizes the 'auto' argument. (Sets the
644 environment variable AUTOBOOT to YES)
645
646 2.2.3 24-Mar-93
647 - Ripped out the 'leave' action. To difficult, and
648 unneeded.

651 - This version is stable enough to post.
652
653 2.2 02-Mar-93
654 - Made wait()'s asynchronous
655 - Changed whole thing to one big state machine
656 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
657 - Added a new type of 'action', called leave. This
658 process will be executed when the system goes from a
659 runlevel specified in it's runlevel field to a
660 level that's not. Nice to bring down NFS and the like.
661
662 2.1 28-Jan-93
663 - Fixed a bug with 'boot' and 'once'.
664 - Check 'initdefault' for validity.
665 - Reckognizes "single" as command line argument.
666 - Retries execvp with 'sh -c exec ..' if command
667 is a shell script. (shouldn't execvp do this?)
668 - Added patches to use syslog if defined.
669
670 2.0 08-Dec-92
671 - Rewrote the code totally, so started with a new
672 version number.

675 run standalone for test purposes.
676
677 1.3, 05-Jul-92
678 - Got a 386, so installed Linux. Added 'soft' reboot
679 to be default under linux. Fixed some typos.
680
681 1.2, 16-Jun-92
682 - Bugreport from Michael Haardt ; removed deadlock
683 and added 'waitpid' instead of 'wait' for SYSV.
684
685 1.1, 30-Apr-92
686 - Read manual wrong: there is no 'action' field called
687 process, but all entries are of type process. Every
688 'process' get exec'ed by /bin/sh -c 'exec command'.
689 - Rapidly respawning processes are caught in the act.
690 - _SYSV support is really Linux support,
691 done by poe@daimi.aau.dk on 25-Mar-92.
692
693 1.0, 01-Feb-92
694 - Initial version, very primitive for the Minix
695 operating system. Required some mods. to the
696 kernel.
