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

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

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

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

164 keep the logging fd open and that is fd#0 aka stdin.

266 * Try to open getenv ("CONSOLE"), /dev/console and /dev/tty0 in order.
267 For backwards compatibility when you try to boot a 2.0.x kernel
268 with a linux > 2.1.70 /dev/console device.
269 * Change src/Makefile for non-debian systems (mainly, RedHat)
270 * Try to create /dev/initctl if not present; check every time to see
271 if the dev/ino of /dev/initctl has changed and re-open it. This should
272 help devfs a bit.
273 * Send SIGUSR1 to init at bootup to let it re-open /dev/initctl;
274 again in support of devfs.

314
315 * Should compile with glibc 1.99 :)
316 * Change behaviour of reboot(1) and halt(1) so that the default when
317 the runlevel can't be determined is to call shutdown.
318 * Added re-exec patch from Al Viro (21 Feb 1998):
319 'U' flag added to telinit. It forces init to re-exec itself
320 (passing its state through exec, certainly).
321 May be useful for smoother (heh) upgrades.
322 24 Feb 1998, AV:
323 did_boot made global and added to state - thanks, Miquel.
324 Yet another file descriptors leak - close state pipe if
325 re_exec fails.

342 * Use strerror() instead of sys_errlist
343 * wall now supports a '-n' option to suppress [most of] the banner.
344 Debian doesn't use sysvinit's wall, but apparently Redhat does.

569 runlevel into utmp file etc)

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

581
582 2.4g 15-May-93

584 hooked up an UPS to the Linux machine. The
585 keyword for catching the TreeFingerSalute is
586 now "ctrlaltdel" instead of "power{wait,fail}".
587
588 2.4a 22-Apr-93
589 - Fixed last to reckognize BSD style wtmp logging.
590 - Changed init to write wtmp records that are
591 SysV compliant but are also reckognized by the
592 BSD last. Added a '+' option to the 'process'
593 field of inittab, for getties that want to do
594 their own utmp/wtmp housekeeping (kludge!).
595 - Now accepts a runlevel on the command line,
596 and reckognizes the 'auto' argument. (Sets the
597 environment variable AUTOBOOT to YES)
598
599 2.2.3 24-Mar-93
600 - Ripped out the 'leave' action. To difficult, and
601 unneeded.

605

607 - Made wait()'s asynchronous
608 - Changed whole thing to one big state machine
609 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
610 - Added a new type of 'action', called leave. This
611 process will be executed when the system goes from a
612 runlevel specified in it's runlevel field to a
613 level that's not. Nice to bring down NFS and the like.
614
615 2.1 28-Jan-93
616 - Fixed a bug with 'boot' and 'once'.
617 - Check 'initdefault' for validity.
618 - Reckognizes "single" as command line argument.
619 - Retries execvp with 'sh -c exec ..' if command
620 is a shell script. (shouldn't execvp do this?)
621 - Added patches to use syslog if defined.
622
623 2.0 08-Dec-92
624 - Rewrote the code totally, so started with a new
625 version number.

628 run standalone for test purposes.
629
630 1.3, 05-Jul-92
631 - Got a 386, so installed Linux. Added 'soft' reboot
632 to be default under linux. Fixed some typos.
633
634 1.2, 16-Jun-92
635 - Bugreport from Michael Haardt ; removed deadlock
636 and added 'waitpid' instead of 'wait' for SYSV.
637
638 1.1, 30-Apr-92
639 - Read manual wrong: there is no 'action' field called
640 process, but all entries are of type process. Every
641 'process' get exec'ed by /bin/sh -c 'exec command'.
642 - Rapidly respawning processes are caught in the act.
643 - _SYSV support is really Linux support,
644 done by poe@daimi.aau.dk on 25-Mar-92.
645
646 1.0, 01-Feb-92
647 - Initial version, very primitive for the Minix
648 operating system. Required some mods. to the
649 kernel.
