3 [ Petter Reinholdtsen ]
4 * Mention new home on Savannah in README.
5 * Revert change from Fedora/RedHat where the now obsolete command
6 INIT_CMD_CHANGECONS was introduced. Based on feedback and patch
7 from Bill Nottingham.
8 * Adjust makefile to make sure the install directories are created
9 before files are copied into them.
10 * Simplify build rules, based on patch from Mike Frysinger and Gentoo.
11 * Fix minor bug in optimizing of argument parsing. Based on
12 report from jakemus on freshmeat.
13 * Add casts to get rid of compiler warning about signed/unsigned issues.
14 * Change tty handling in init to make sure the UTF-8 flag is not cleared
15 on boot. Patch from Samuel Thibault.
16 * Add Makefile in toplevel directory.
17 * Print usage information when shutdown is used by non-root user.
18 Patch from Mike Frysinger and Gentoo.
19 * Sync shutdown manual page and usage information. Patch from Mike
20 Frysinger and Gentoo.
21 * Fix race condition in utmp writing. Patch from Gil Kloepfer via
22 Mike Frysinger and Gentoo.
23 * Rewrite findtty() in bootlogd to recursively search /dev/ for the
24 correct device, to handle terminal devices for example in /dev/pty/.
25 Patch from Debian.
26 * Make sure bootlogd findpty() returns an error value when it fails to
27 find a usable pty. Patch from Rob Leslie via Debian.
28 * Make sure bootlogd fflush() every line, even if asked not to flush
29 to disk using fdatasync(). Patch from Scott Gifford via Debian.

31 [ Werner Fink ]
32 * Add the comment from Andrea Arcangeli about the correct
33 place of setting the default childhandler within spawn().
34 * Make sure that newline is printed out for last(1) even
35 if an utmp record entry is truncated.
36 * Check if utmp not only exists but also is writable and delay
37 writing out of the utmp runlevel record if utmp is not writable.
38 * Be able to find libcrypt also on 64 bit based architectures.
39 * Add option -w to the last command to display the full user and
40 domain names in the output. Patch from Petr Lautrbach.
41 * Add a manual page for utmpdump as this tool is sometimes
42 very useful even if not intended for normal use.
43 * Use paths.h macros for wall
44 * Change path "/etc/powerstatus" to "/var/run/powerstatus"
45 * Detected also removable block devices at halt/reboot to be able
46 to flush data and send them the ATA standby command. This should
47 avoid data loss on USB sticks and other removable block devices.
48 * Flush block devices on halt/reboot if not done by the kernel.
49 * Set SHELL to /bin/sh in the environmant of shutdown.
50 * Retry to write out shutdown messages if interrupted.
51 * pidof/killall5 - make omit pid list a dynamic one.
52 * pidof - provide '-n' to skip stat(2) syscall on network based FS.
53 * init - avoid compiler warnings
54 * init - initialize console by using the macros from ttydefaults.h
55 * init - add the possiblity to ignore further interrupts from keyboard
56 * init - add the possiblity to set sane terminal line settings
57 * sulogin - add the possibility to reset the terminal io
58 * Fix some minor problems
59 * init - enable is_selinux_enabled() to detect selinuxfs
60 * Add fix for Debian bug #536574 -- Can be enabled by -DACCTON_OFF
61 * Add helper program fstab-decode to make it easier to handle
62 /etc/mtab content. Patch by Miloslav Trmac and Fedora.
63 * Add fix for Debian bug #335023 - Make sure TERM is set on FreeBSD.
64 * Add fix for Debian bug #374038 - Make it clear that shutdown -c can
65 only cancel a waiting shutdown, not an active one.
66 * Add note to pidof manual page about the use of readlink(2). Patch by
67 Bill Nottingham and Fedora.
68 * Add changes for Debian bug #68621 - Add PAM support for programs spawned
69 by init on the console like sulogin. Based on patch by Topi Miettinen.
70 * Test out PAM support, extend PAM support by providing environment
71 is specified by /etc/pam.d/init
72 * Move utmp/wtmp before the execvp() in spawn() to be sure to
73 use the correct pid even on a controlling tty
74 * Remaining problem is that the pid of the second fork() for
75 getting a controlling tty isn't that reported by spawn()
76 * Re-enable writting utmp/wtmp for boot scripts
77 * Provide a simply /etc/pam.d/init as without it will not work (sigh!)

91 the time between downs. Fix typo in string compare in last.c.
92 Patch by Thomas Hood.
93 * Improve handling of IPv6 addresses in last. Patch from Fedora.
94 * Document last options in usage information, previously only
95 mentioned in the manual page.
96 * Add new option -F to last, to output full date string instead
97 of the short form provided by default. Patch from Olaf Dabrunz
98 and SuSe.
99 * Adjust build rules to make sure the installed binaries
100 are stripped.
101 * Increase the compiler warning level when building.
102 * Fix utmp/wtmp updating on 64-bit platforms. Patch by Bill
103 Nottingham and Fedora.

105 Patch from Christian 'Dr. Disk' Hechelmann and Fedora.
106 * Make sure to use execle and no execl when passing environment to
107 the new process. Patch from RedHat.
108 * Correct init to make sure the waiting status is preserved across
109 re-exec. Patch from RedHat.
110 * Correct init to avoid race condition when starting programs during
111 boot. Patch from SuSe.
112 * Allow 'telinit u' in runlevels 0 and 6. Patch from Thomas Hood.
113 * Change install rules to make pidof an absolute symlink. Patch from
114 Thomas Hood.
115 * Improve error message from init if fork() fail. Patch found in Suse.
116 * Add support for SE Linux capability handling. Patch from Manoj
117 Srivastava, adjusted to avoid aborting if SE policy was loaded in
118 the initrd with patch from Bill Nottingham and Fedora.
119 * Add -c option to pidof for only matching processes with the same
120 process root. Ignore -c when not running as root. Patch from
121 Thomas Woerner and Fedora.
122 * Adjust init to terminate argv0 with one 0 rather than two so that
123 process name can be one character longer. Patch by Kir Kolyshkin.
124 * Make sure bootlogd exit with non-error exit code when forking of
125 the child successfully.
126 * Add bootlogd option -s to make it possible to control the use of
127 fdatasync(). Patch from Thomas Hood.
128 * Add bootlogd option -c to tell it to create the log file if it does
129 not exist. Patch from Thomas Hood.
130 * Let bootlogd also look at ttyB* devices to work on HPPA. Patch
131 from Thomas Hood.
132 * Change init to use setenv() instead of putenv, make sure the PATH
133 value is usable on re-exec. Patch from Thomas Hood.
134 * Add usleep in killall5 after killing processes, to force the kernel
135 to reschedule. Patch from SuSe.
136 * Modify pidof to not print empty line if no pid was found.
137 * Modify init and sulogin to fix emergency mode's tty, making sure ^C
138 and ^Z work when booting with 'emergency' kernel option. Patch from
139 Samuel Thibault.
140 * Modify init to allow some time for failed opens to resolve themselves.
141 Patch from Bill Nottingham and Fedora.
142 * Modify init to shut down IDE, SCSI and SATA disks properly. Patches
143 from Sebastian Reichelt, Werner Fink and SuSe.
144 * Modify wall to use UT_LINESIZE from <utmp.h> instead of hardcoded
145 string lengths. Patch from SuSe.
146 * Change wall to make halt include hostname in output.
147 * Change killall to avoid killing init by mistake. Patch from SuSe.
148 * Change killall5 to use the exit value to report if it found any
149 processes to kill. Patch from Debian.
150 * Add option -o opmitpid to killall5, to make it possible to skip
151 some pids during shutdown. Based on patch from Colin Watson and
152 Ubuntu.
153 * Add references between killall5 and pidof manual pages. Patch from Debian.
154 * Modify killall to work better with user space file system, by
155 changing cwd to /proc when stopping and killing processes, and
156 avoiding stat() when the value isn't used. Also, lock process
157 pages in memory to avoid paging when user processes are stopped.
158 Patch from Debian and Goswin von Brederlow with changes by Kel
159 Modderman.
160 * Change shutdown to only accept flags -H and -P with the -h flag,
161 and document this requirement in the manual page.
162 * Change reboot/halt to work properly when used as a login shell.
163 Patch by Dale R. Worley and Fedora.
164 * Let sulogin fall back to the staticly linked /bin/sash if both roots
165 shell and /bin/sh fail to execute.

170
171 * Fixed up bootlogd to read /proc/cmdline. Also keep an internal
172 linebuffer to process \r, \t and ^H. It is becoming useable.
173 * Applied trivial OWL patches
174 * Block signals in syslog(), since syslog() is not re-entrant
175 (James Olin Oden <joden@malachi.lee.k12.nc.us>, redhat bug #97534)
176 * Minor adjustements so that sysvinit compiles on the Hurd
177 * killall5 now skips kernel threads
178 * Inittab entries with both 'S' and other runlevels were broken.
179 Fix by Bryan Kadzban <bryan@kadzban.is-a-geek.net>
180 * Changed initreq.h to be more flexible and forwards-compatible.
181 * You can now through /dev/initctl set environment variables in
182 init that will be inherited by its children. For now, only
183 variables prefixed with INIT_ can be set and the maximum is
184 16 variables. There's also a length limit due to the size
185 of struct init_request, so it should be safe from abuse.
186 * Option -P and -H to shutdown set INIT_HALT=POWERDOWN and
187 INIT_HALT=HALT as environment variables as described above
188 * Add "mountpoint" utility.
189 * Slightly better algorithm in killall5.c:pidof()
190 * Added some patches from fedora-core (halt-usage, last -t,
191 sulogin-message, user-console)

196
197 * Add IPv6 support in last(1)
198 * Sulogin: even if the root password is empty, ask for a password-
199 otherwise there is no way to set a timeout.
200 * Removed support for ioctl.save.
201 * Turned of support for /etc/initrunlvl and /var/run/initrunlvl
202 * Fixed warts in dowall.c ("Dmitry V. Levin" <ldv@altlinux.org>)
203 * Fix init.c::spawn(). The "f" variable was used both as file descriptor
204 and waitpid(2) return code. In certain circumstances, this leads to
205 TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).
206 * Fix fd leak in sulogin (Dmitry V. Levin).
207 * More error checking in all wait() calling code (Dmitry V. Levin).
208 * Fix argv[] initialization in spawn() (Dmitry V. Levin).
209 * Change strncpy to strncat in most places (Dmitry V. Levin).

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

335 * Try to create /dev/initctl if not present; check every time to see
336 if the dev/ino of /dev/initctl has changed and re-open it. This should

383 * Added re-exec patch from Al Viro (21 Feb 1998):
384 'U' flag added to telinit. It forces init to re-exec itself
385 (passing its state through exec, certainly).
386 May be useful for smoother (heh) upgrades.

489 /var/log and /etc itself.

634 runlevel into utmp file etc)
635 - now using "reliable" signals instead of V7 style.
636 - Updated all scripts. Examples are in two directories:
637 etc (normal) and etc-sysv (sysv style scripts).

645 SysVinit-2.4.tar.z.
646
647 2.4g 15-May-93
648 - Changed init to really catch SIGPWR 'cause we
649 hooked up an UPS to the Linux machine. The
650 keyword for catching the TreeFingerSalute is
651 now "ctrlaltdel" instead of "power{wait,fail}".
652
653 2.4a 22-Apr-93
654 - Fixed last to reckognize BSD style wtmp logging.
655 - Changed init to write wtmp records that are
656 SysV compliant but are also reckognized by the
657 BSD last. Added a '+' option to the 'process'
658 field of inittab, for getties that want to do
659 their own utmp/wtmp housekeeping (kludge!).
660 - Now accepts a runlevel on the command line,
661 and reckognizes the 'auto' argument. (Sets the
662 environment variable AUTOBOOT to YES)
663
664 2.2.3 24-Mar-93
665 - Ripped out the 'leave' action. To difficult, and
666 unneeded.

670
671 2.2 02-Mar-93
672 - Made wait()'s asynchronous
673 - Changed whole thing to one big state machine
674 - Now using 'pseudo levels' # & * for SYSINIT & BOOT
675 - Added a new type of 'action', called leave. This
676 process will be executed when the system goes from a
677 runlevel specified in it's runlevel field to a
678 level that's not. Nice to bring down NFS and the like.
679
680 2.1 28-Jan-93
681 - Fixed a bug with 'boot' and 'once'.
682 - Check 'initdefault' for validity.
683 - Reckognizes "single" as command line argument.
684 - Retries execvp with 'sh -c exec ..' if command
685 is a shell script. (shouldn't execvp do this?)

687
688 2.0 08-Dec-92
689 - Rewrote the code totally, so started with a new
690 version number.

693 run standalone for test purposes.
694
695 1.3, 05-Jul-92
696 - Got a 386, so installed Linux. Added 'soft' reboot
697 to be default under linux. Fixed some typos.
698
699 1.2, 16-Jun-92
700 - Bugreport from Michael Haardt ; removed deadlock
701 and added 'waitpid' instead of 'wait' for SYSV.
702
703 1.1, 30-Apr-92
704 - Read manual wrong: there is no 'action' field called
705 process, but all entries are of type process. Every
706 'process' get exec'ed by /bin/sh -c 'exec command'.
707 - Rapidly respawning processes are caught in the act.
708 - _SYSV support is really Linux support,
709 done by poe@daimi.aau.dk on 25-Mar-92.
710
711 1.0, 01-Feb-92
712 - Initial version, very primitive for the Minix
713 operating system. Required some mods. to the
714 kernel.
