27 * Fix typos and do minor updates in the manual pages.
28 * Correct section of mountpoint(1).
29 * Document -e and -t options for telinit in init(8).
30 * Update address of FSF in the COPYRIGHT file.
31 * Document in halt(8) that -n might not disable all syncing.
32 Patch by Bill Nottingham and Fedora
33 * Adjust output from "last -x". In reboot lines, print endpoint
34 of uptime too. In shutdown lines print downtimes rather than
35 the time between downs. Fix typo in string compare in last.c.
36 Patch by Thomas Hood.
37 * Improve handling of IPv6 addresses in last. Patch from Fedora.
38 * Document last options in usage information, previously only
39 mentioned in the manual page.
40 * Add new option -F to last, to output full date string instead
41 of the short form provided by default. Patch from Olaf Dabrunz
42 and SuSe.
43 * Adjust build rules to make sure the installed binaries
44 are stripped.
45 * Increase the compiler warning level when building.
46 * Fix utmp/wtmp updating on 64-bit platforms. Patch by Bill
47 Nottingham and Fedora.
48 * Avoid unchecked return value from malloc() in utmpdump.
49 Patch from Christian 'Dr. Disk' Hechelmann and Fedora.
50 * Make sure to use execle and no execl when passing environment to
51 the new process. Patch from RedHat.
52 * Correct init to make sure the waiting status is preserved across
53 re-exec. Patch from RedHat.
54 * Correct init to avoid race condition when starting programs during
55 boot. Patch from SuSe.
56 * Allow 'telinit u' in runlevels 0 and 6. Patch from Thomas Hood.
57 * Change install rules to make pidof an absolute symlink. Patch from
58 Thomas Hood.
59 * Improve error message from init if fork() fail. Patch found in Suse.
60 * Add support for SE Linux capability handling. Patch from Manoj
61 Srivastava, adjusted to avoid aborting if SE policy was loaded in
62 the initrd with patch from Bill Nottingham and Fedora.
63 * Add -c option to pidof for only matching processes with the same
64 process root. Ignore -c when not running as root. Patch from
65 Thomas Woerner and Fedora.
66 * Adjust init to terminate argv0 with one 0 rather than two so that
67 process name can be one character longer. Patch by Kir Kolyshkin.
68 * Make sure bootlogd exit with non-error exit code when forking of
69 the child successfully.
70 * Add bootlogd option -s to make it possible to control the use of
71 fdatasync(). Patch from Thomas Hood.

73 not exist. Patch from Thomas Hood.
74 * Let bootlogd also look at ttyB* devices to work on HPPA. Patch
75 from Thomas Hood.
76 * Change init to use setenv() instead of putenv, make sure the PATH
77 value is usable on re-exec. Patch from Thomas Hood.
78 * Add usleep in killall5 after killing processes, to force the kernel
79 to reschedule. Patch from SuSe.
80 * Modify pidof to not print empty line if no pid was found.
81 * Modify init and sulogin to fix emergency mode's tty, making sure ^C
82 and ^Z work when booting with 'emergency' kernel option. Patch from
83 Samuel Thibault.
84 * Modify init to allow some time for failed opens to resolve themselves.
85 Patch from Bill Nottingham and Fedora.
86 * Modify init to shut down IDE, SCSI and SATA disks properly. Patches
87 from Sebastian Reichelt, Werner Fink and SuSe.

89 string lengths. Patch from SuSe.
90 * Change wall to make halt include hostname in output.
91 * Change killall to avoid killing init by mistake. Patch from SuSe.
92 * Change killall5 to use the exit value to report if it found any
93 processes to kill. Patch from Debian.
94 * Add option -o opmitpid to killall5, to make it possible to skip
95 some pids during shutdown. Based on patch from Colin Watson and
96 Ubuntu.
97 * Add references between killall5 and pidof manual pages. Patch from Debian.
98 * Modify killall to work better with user space file system, by
99 changing cwd to /proc when stopping and killing processes, and
100 avoiding stat() when the value isn't used. Also, lock process
101 pages in memory to avoid paging when user processes are stopped.
102 Patch from Debian and Goswin von Brederlow with changes by Kel
103 Modderman.
104 * Change shutdown to only accept flags -H and -P with the -h flag,
105 and document this requirement in the manual page.
106 * Change reboot/halt to work properly when used as a login shell.
107 Patch by Dale R. Worley and Fedora.

114
115 * Fixed up bootlogd to read /proc/cmdline. Also keep an internal
116 linebuffer to process \r, \t and ^H. It is becoming useable.
117 * Applied trivial OWL patches
118 * Block signals in syslog(), since syslog() is not re-entrant
119 (James Olin Oden <joden@malachi.lee.k12.nc.us>, redhat bug #97534)
120 * Minor adjustements so that sysvinit compiles on the Hurd
121 * killall5 now skips kernel threads
122 * Inittab entries with both 'S' and other runlevels were broken.
123 Fix by Bryan Kadzban <bryan@kadzban.is-a-geek.net>
124 * Changed initreq.h to be more flexible and forwards-compatible.
125 * You can now through /dev/initctl set environment variables in
126 init that will be inherited by its children. For now, only
127 variables prefixed with INIT_ can be set and the maximum is
128 16 variables. There's also a length limit due to the size
129 of struct init_request, so it should be safe from abuse.
130 * Option -P and -H to shutdown set INIT_HALT=POWERDOWN and
131 INIT_HALT=HALT as environment variables as described above
132 * Add "mountpoint" utility.
133 * Slightly better algorithm in killall5.c:pidof()
134 * Added some patches from fedora-core (halt-usage, last -t,
135 sulogin-message, user-console)

141 * Add IPv6 support in last(1)
142 * Sulogin: even if the root password is empty, ask for a password-
143 otherwise there is no way to set a timeout.
144 * Removed support for ioctl.save.
145 * Turned of support for /etc/initrunlvl and /var/run/initrunlvl
146 * Fixed warts in dowall.c ("Dmitry V. Levin" <ldv@altlinux.org>)
147 * Fix init.c::spawn(). The "f" variable was used both as file descriptor
148 and waitpid(2) return code. In certain circumstances, this leads to
149 TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).
150 * Fix fd leak in sulogin (Dmitry V. Levin).
151 * More error checking in all wait() calling code (Dmitry V. Levin).
152 * Fix argv[] initialization in spawn() (Dmitry V. Levin).
153 * Change strncpy to strncat in most places (Dmitry V. Levin).

159 * Don't use /etc/initlvl interface for telinit; only use /dev/initctl,
160 and give a clear error when that fails.
161 * Add -i/--init command line flag to init - this tells init
162 'behave as system init even if you're not PID#1'. Useful for
163 testing in chroot/jail type environments.

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

325 * Change behaviour of reboot(1) and halt(1) so that the default when
326 the runlevel can't be determined is to call shutdown.
327 * Added re-exec patch from Al Viro (21 Feb 1998):
328 'U' flag added to telinit. It forces init to re-exec itself
329 (passing its state through exec, certainly).
330 May be useful for smoother (heh) upgrades.
331 24 Feb 1998, AV:
332 did_boot made global and added to state - thanks, Miquel.
333 Yet another file descriptors leak - close state pipe if

572
573 2.50 14-Feb-1994
574 - Ignores unknown command line arguments.
575 - Modelled more after the "real" sysVinit
576 - Lots of changes all over the place.
577 (like showing runlevel in "ps" listing, logging
578 runlevel into utmp file etc)
579 - now using "reliable" signals instead of V7 style.
580 - Updated all scripts. Examples are in two directories:
581 etc (normal) and etc-sysv (sysv style scripts).

586
587 2.4 24-May-93

589 SysVinit-2.4.tar.z.
590
591 2.4g 15-May-93
592 - Changed init to really catch SIGPWR 'cause we
593 hooked up an UPS to the Linux machine. The
594 keyword for catching the TreeFingerSalute is
595 now "ctrlaltdel" instead of "power{wait,fail}".
596
597 2.4a 22-Apr-93
598 - Fixed last to reckognize BSD style wtmp logging.
599 - Changed init to write wtmp records that are
600 SysV compliant but are also reckognized by the
601 BSD last. Added a '+' option to the 'process'
602 field of inittab, for getties that want to do
603 their own utmp/wtmp housekeeping (kludge!).
604 - Now accepts a runlevel on the command line,
605 and reckognizes the 'auto' argument. (Sets the
606 environment variable AUTOBOOT to YES)
607
608 2.2.3 24-Mar-93
609 - Ripped out the 'leave' action. To difficult, and
610 unneeded.
611 - Going single user now kills _all_ processes.
612 - Added '-t secs' option to all commands.
613 - This version is stable enough to post.
614
615 2.2 02-Mar-93
616 - Made wait()'s asynchronous
617 - Changed whole thing to one big state machine
618 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
619 - Added a new type of 'action', called leave. This
620 process will be executed when the system goes from a
621 runlevel specified in it's runlevel field to a
622 level that's not. Nice to bring down NFS and the like.
623
624 2.1 28-Jan-93
625 - Fixed a bug with 'boot' and 'once'.
626 - Check 'initdefault' for validity.
627 - Reckognizes "single" as command line argument.
628 - Retries execvp with 'sh -c exec ..' if command
629 is a shell script. (shouldn't execvp do this?)
630 - Added patches to use syslog if defined.
631
632 2.0 08-Dec-92
633 - Rewrote the code totally, so started with a new
634 version number.
635 - Dropped Minix support, this code now is Linux - specific.
636 - With TEST switch on, this init & telinit can
637 run standalone for test purposes.
638
639 1.3, 05-Jul-92
640 - Got a 386, so installed Linux. Added 'soft' reboot
641 to be default under linux. Fixed some typos.
642
643 1.2, 16-Jun-92
644 - Bugreport from Michael Haardt ; removed deadlock
645 and added 'waitpid' instead of 'wait' for SYSV.
646
647 1.1, 30-Apr-92
648 - Read manual wrong: there is no 'action' field called
649 process, but all entries are of type process. Every
650 'process' get exec'ed by /bin/sh -c 'exec command'.
651 - Rapidly respawning processes are caught in the act.
652 - _SYSV support is really Linux support,
653 done by poe@daimi.aau.dk on 25-Mar-92.
654
655 1.0, 01-Feb-92
656 - Initial version, very primitive for the Minix
657 operating system. Required some mods. to the
658 kernel.
