Raw Blame History

sysvinit (2.94) unreleased; urgency=low
[ Jesse Smith ]
* When the halt command is called with the -p flag (or as poweroff)
the command now passes the "-h -P" flags to shutdown. This
in turn sets the INIT_HALT environment variable to POWEROFF.
Assuming this value is checked by initscripts during the
shutting down procedure, it should cause the system to
be powered off.
If halt is called without -p then the value of INIT_HALT
is not set and the default action (often set in /etc/defaut/halt)
is taken.
sysvinit (2.93) released; urgency=low
[ Jesse Smith ]
* Fixed error where pidof would not omit checking PIDs passed
to it when the -o flag was used.
Fixes Debian bug #913394.
sysvinit (2.92) released; urgency=low
[ Jesse Smith ]
* The shutdown and init commands were using different default delays between
sending processes SIGTERM and SIGKILL - they were 3 and 5 seconds, respectively.
Unified these on 3 seconds, using a new defined value in init.h.
Updated shutdown manual page to reflect the change and better explain
how -t and -n flags work.
Updated the init manual page with the new default value.
The updated documentation resolves Debian bug #375274.
* Remove PC speaker beep from shutdown process in dowall.c.
Closes Debian bug #614893.
Patch provided by Andreas Fackler.
* Removed unused Version variable from wall.c.
* Updated halt/reboot manual page to acknowledge the -i
flag may not properly shut down network interfaces if the interface
does not have an IP address.
Addresses Debian bug #361935.
* Applied patch from Daniel Povey which should allow killall5/pidof to
avoid locking up if it encounters stopped or zombie processes
due to broken NFS mount points.
This should allow Debian bug #719273 to be closed.
* Applied patch from Regid Ichira to clarify shutdown command
line options. Updated manual page for shutdown.
Closes Debian bug #630661.
* shutdown command was setting environment variable INIT_HALT to
"POWERDOWN", this should have been "POWEROFF" as specified in the
manual page. Fixed code to match manual page and init scripts.
Closes Debian bugs #717531 and #590895
* Added -l flag to "last" command. When used it allows "last" to
display usernames longer than 8 characters long.
* Added -q and -Q flags to shutdown command to make the "system is going down"
message appear less often. The -q flag causes messages to only appear at the
10 minute, 5 minute and x-hour intervals.
The -Q flag maintains complete silence up until the final "now" warning.
* Mention GRUB as a potential boot loader in init page since LILO is
rarely used anymore, outside of Slackware.
* Swapped out ECHOPRT for ECHOE in stty settings when init brings up
emergency console. Should make backspace-erasing characters work
more naturally.
Closes Debian bug #402847.
* Updated src/Makefile to make sure we build all the software before
attempting to install.
* Removed typos from pidof manual page and killall5 page.
Closes Debian bugs #815839, #905245 and #890478
* Added -f <format> option to pidof program to allow printf
style formating.
Closes Debian bug #571590
Thanks to Philipp Marek for the patch.
* Added new tool (readbootlog) which will read the /var/log/boot file
produced by bootlogd. The output is displayed cleaned up so there
are no control characters. This avoids the need to use sed or related
tools to try to clean up the contents of the log.
* Added manual page for readbootlog program. Updated bootlogd page
to reference it. Closes Debian bug #725123.
* Updated the shutdown manual page to try to make it more clear
where we are talking about an initscript called halt or the halt
program. Likewise whether we are talking about the shutdown process
or the specific shutdown program.
Should address Debian bug #374039.
* Added patch from Samuel Thibault to make project compile
on Hurd branch of Debian.
sysvinit (2.91) world; urgency=low
[ Jesse Smith ]
* Adjusted order of compile flags to make it easier for downstream
to adjust optimization level. Patch provided by Matias Fonzo.
Can now set optimization level in CFLAGS variable.
* Added --version command line flag to display current version info.
Updated manual page for init.8 to match.
* Version information is now fetched and defined by the Makefile.
No more need to update the version manually in the init.c source.
* The init process now writes the current runlevel to /var/run/runlevel.
This information can be read by the "runlevel" command as well as "halt"
and "reboot". Having the information logged in /var/run/runlevel as
well as the utmp file means systems without utmp (like those running
the musl C library) can still check the current runlevel. This is
useful when running halt/reboot as these programs want to check the
runlevel.
* Added patch from Walter Harms which allows pidof to run without
displaying output. In this mode pidof simply returns true or false
without displaying PID values.
Updated manual page with new -q (quiet) mode.
Added -h flag for pidof, which was recognized before, but not used.
The -h flag now displays brief usage information for pidof.
* Added check for kernel parameter init.autocon=1. If this exists, then
init will try to open its own console. If not, then any console=
parameters will be ignored. This avoids conflicts with native kernel
created consoles.
sysvinit (2.90) world; urgency=low
[ Jesse Smith ]
* Updated some comments in init.c to answer questions or
remove old notes we no longer need.
* Removed unneeded "count" variable in utmpdump.c.
* Fixed typo in accidental wrote_wtmp_rlevel == 0 || wrote_wtmp_rlevel
comparison so the latter is wrote_utmp_rlevel.
* Simplified logic in mountpoint.c when testing for same device or same inode.
Thanks to David Binderman for pointing out the above three issues.
* When we run shutdown and then the computer is put to sleep, the
shutdown command recognizes time has passed and continues its
countdown taking the time lapse into consideration. This prevents
longer waits if we slept past the time we should have shutdown.
Accurate to the nearest minute.
Closes Savannah bug #36279.
* Added document article and manual page for the initctl (/run/initctl)
named pipe. Makes it easier for people to communicate with and
extend communication to init.
* Added check that named pipe is open before trying to close it
when something goes wrong or we receive SIGUSER1. Avoids potential
crash if we receive SIGUSR1 while pipe is not open.
* Added new signal handler for SIGUSR2. When init receives SIGUSR2
it closes (and leaves closed) the named pipe /run/initctl. This
can be used to make sure init does not have any files open. However,
it also means we cannot switch run levels or bring down the system.
The pipe can be re-opened by sending init the SIGUSR1 signal.
* Added "Fall through" comments to some switch statements where multiple
approaches are tried in order to prevent warnings from GCC 7 (and newer).
(Thanks to Matias Fonzo for this fix.)
* Added includes on Linux for sys/sysmacros.h as the old defines in
the sys/types.h file will be removed in the future.
(Thanks to Matias Fonzo for this fix.)
* Removed old LSM file.
Added .gitignore files to avoid git tracking object files.
Removed old start-stop-daemon from contrib directory.
(Patches provided by Guillem Jover.)
* Cleaned up most warnings generated by GCC 7 & 8. We still
get some from faulty "nonstring" reports, but silencing them on
GCC 8 results in more warnings on GCC 7 and Clang, so leaving them
for now.
* Fixed compile error on Fedora 28 where crypt() will not link due to
undocumented dependency change.
* Updated Makefile to make sure correct version number and correct
version of files are used. Makefile was pulling from master to create
tarballs with old version information when trying to create beta
snapshot.
* Updated version information in init.c
* Updated compiler flag from -fstack-protector to -fstack-protector-strong
for better protection.
* Cleaned up toplevel Makefile so it stops creating unnecessary temporary
directories.
* Fixed typo in mountpoint.c. Patch provided by Radostin Stoyanov.
sysvinit (2.89) world; urgency=low
[ Jesse Smith ]
* Updated mountpoint command with -p flag. The -p flag causes
mountpoint to search for circular mount points. For example, if
/a/b/c/d is a mount point for /a/b then the former is a valid
mount point. This only works on Linux since it uses /proc/mounts.
Updated manual page to match. This fix closes Savannah bug #37114.
* Removed two sleep calls when we are doing sync anyway to make sure
data is being written. Speeds up reboot time by about two seconds.
* Fixed Clang compiler warning regarding variable data parameters to sprintf().
* Updated top-level Makefile to work with git repo instead of old svn repo.
* Removed unused variables and findtty() function in bootlogd
* Add checks to return code for fscanf() called in init.c.
This mostly just cleans up compiler warnings.
* Perform error check on setuid() call as suggested in manual page.
* Fix typo in killall5.c
Move initscript sample file from "src" to "doc" directory and updated
Makefile to match.
* Allow multiple console output
When booting a kernel with multiple serial console support, or multuiple
console arguments ala "console=tty1 console=ttyS0,9600" the kernel will output
messages to all consoles, init however will not. It will only send output to,
and accept input from, the last of the consoles.
This patch fixes it.
(Patch provided by Martin Buck.)
* Added Patch from Debian developer Mats Erik Andersson to make
ioctl work on GNU/kFreeBSD. Patches bootlogd.
* Added Robert Millan's Debian patch to set TERM variable to xterm (instead
of cons25) when running on GNU/kFreeBSD.
* Added Robert Millan's Debian patch to use /run/initctl as the named
pipe for communicating. This works around a limitation on the kFreeBSD
branch which prevents us from using /dev/initctl for pipes.
* Confirmed we have applied Guillem Jover's patch to make
ifdown work on FreeBSD.
* Confirmed we have Debian patch to fix enabling SELinux.
(Credit to Petter Reinholdtsen)
* Confirmed we have Debian patch to make sure utf-8 flag is not cleared from tty.
(Credit to Samuel Thibault)
* Confirmed we have Roger Leigh's Makefile patch to allow building
with multiarch libcrypt.
* Applied Justus Winter's symlink patch to make sure killall5
builds and runs on Hurd.
* Confirmed we have Werner Fink's PATH_MAX patch for getting
killall5 to build on Hurd.
* Made sure we have Petter Reinholdtsen's patch to init.c which
allows init to build on GNU/kFreeBSD despite missing VSWTC.
* Dropping Debian patch to use /run/nologin instead of /etc/nologin in paths.h.
Seems every distribution uses a different location. Oracle uses /etc/nologin,
CentOS seems to use /var/run/nologin.
We will use /etc/nologin and let distros patch to suit their own preference.
* Updated halt.8 man page with corrections from
Christoph Anton Mitterer.
* Confirmed we have applied patch from Bjarni Ingi Gislason
which fixes typo in fstab-decode man page.
* Applied Debian patch to allow init to build on GNU Hurd.
(Credit: Roger Leigh)
* Confirmed we have Debian patch from developer Johannes Truschnigg
which informs the user of field size limit.
* Applied patch from Debian to the init manual page (init.8)
to better address runlevels. (Author unknown)
* The pidof command used to discover the correct PID of
a process even if the wrong path was given. For example
pidof /wrongpath/sleep would find the PID of a command run as "sleep".
This bug was reported on Launchpad for Ubuntu and on Savannah.
https://bugs.launchpad.net/ubuntu/+source/sysvinit/+bug/1546126
http://savannah.nongnu.org/bugs/?47196
This bug appears to have been fixed in the development branch,
allowing these bugs to be tested/closed.
* Confirmed Savannah bug #37114 (mountpoint does not detect
mount points using --bind on same file system) still exists,
but fixed in Debian and Red Hat.
Considering this bug closed since distributions are using
util-linux's mountpoint program and ours is no longer
built/used by default.
Considered importing util-linux mountpoint but that would duplicate
effort and pull in a new dependency on libmount.
* Problem with pidof breaks after prelink (Savannah bug #34992)
fixed. Patch supplied by Dave Dykstra.
* Patch to automatically spawn a getty on kernel consoles
The feature is useful for developers and admins that occasionally need
to boot with e.g. console=ttyS0.
The built in default can be overridden via inittab for each device. An
entry like "S0::off:" turns off the getty on ttyS0.
characters in log file. Also makes parsing easier.
This should close Savannah bug report 36528.
http://savannah.nongnu.org/bugs/?36528
* Applied patches provided in Savannah bug report 49991. Fix tabs in
bootlogd and avoid printing unitialized "buf" variable when
consolename() fails.
[ Werner Fink ]
* Do not forget room for last NULL of new environment (was
local bug 35866)
* Handle deleted binaries in pidof (was local bug #34992)
* Allow init to delete extra environment variables (was local bug
#35858)
* Avoid that init double environment variables for its childs
(was local bug #35855)
* Remove man-db tag for encoding for canonical man
* Sulogin: try to detect the real device(s) used for the system console
/dev/console if but only if /dev/console is used. On Linux this can
be more than one device, e.g. a serial line as well as a virtual
console as well as a simple printer.
* Fix counting message lines in wall. Patch from Petr Lautrbach.
* Fix bad printf conversion specifier in wall. Patch from Sébastien Luttringer.
* Add patches from Openwall project. Thanks goes to Solar Designer.

Navdeep Bhatia (see local bug #32429)
* Fix signal and alarm handling based on the patch from Florent Viard.
(was local bug #32304)
* Add fix for Redhat bug #573346: last incorrectly displays IPv6
addresses (was local bug #29497)
* Correct fix for Debian bug #547073: use IUTF8 flag if defined
and if already set to make sure the utf-8 flag is not cleared
from the tty. Patch from Samuel Thibault.
* Include limits.h in killall.c to enforce definition of PATH_MAX
* Fix sysvinit bug #29758 Linker invocation should not contain
headers. Change based on patch from Elias Pipping.
* Add fix for Debian bug #580272: use return value 1 of
is_selinux_enabled() to determine if SELinux is enabled,
otherwise initialize SELinux and load the policy. Patch from
Petter Reinholdtsen.
* Make quotes visible in example of the manual page of fstab-decode
* Sulogin: enforce reconnection of stdin/stdout/stderr if a device
was specified.
* Sulogin: if zero is read at reading the passwd guess it's done.
* Sulogin: respect byte order that is do not mix chars and ints
* Shutdown: use PATH_DEFAULT as suggested by Paul Arthur in local bug #36101
* Killall5/pidof: handle strange names of executables (local bug #36252)
* Sulogin: be aware the crypt(3) may fail (local bug #36313)
[ Petter Reinholdtsen ]
* Next release will be 2.89dsf.
* Add #ifdef in bootlogd.c to avoid gcc warnings about unused
variable on non-linux platforms.
* Only set the VSWTC field for termios in init if it is available,
to get the source building on FreeBSD.
* Add some code to be able to detect programs even as user with
kernel 3.0 and above
* Improve message printed when signaling processes to stop.
Patch from Matias A. Fonzo at the dragora project.
* Rename internal functions warn() and shutdown() in the shutdown
binary to avoid surprising dynamic library name resolution
conflict with NSS modules. Patch from Richard Tollerton.
* Try harder to find libcrypt.*, even if there is no static library
available. Also look in /usr/lib/*/ for the library, to handle
Debian multiarch systems. Based on patch from Andrew Gregory.
* Adjust included headers to be compatible with the musl C
library. Patch from Matias A. Fonzo and Dragora.
* Move dovoid() macro from #ifdef__GLIBC__ to #ifdef __linux__,
to match the condutions of the place where it is used. Thanks
to Matias A. Fonzo for noticing.
* Define _XOPEN_SOURCE when building to get crypt() from <unistd.h>
instead of using <crypt.h> in sulogin.c, to get the source building
with the musl C library.
* Use sysconf(_SC_SYMLOOP_MAX) instead of MAXSYMLINKS. If sysconf
returns an error, fall back to MAXSYMLINKS on platforms that
define it. Fixes build on Hurd. Patch from Justus Winter and
Debian.
* Adjust makefile to make it easier to link all binaries statically.
Patch from Matias A. Fonzo and Dragora.
* Rewrite findtty() in bootlogd.c to not chance working directory, to
reduce the amount of failure that can happin in that function.
* Adapt bootlogd TIOCCONS call to kfreebsd. Patch from Mats Erik
Andersson and Debian.
* Document length limit for the process field in the inittab. Patch
from Johannes Truschnigg and Debian.
* Fix typo in fstab-decode(8) font escape. Patch from Bjarni Ingi
Gislason and Debian.
* Port ifdown.c to FreeBSD. Patch from Guillem Jover and Debian.
* Drop dsf part from version number. It no longer make sense to keep.
* Remove obsolete/ directory from tarball. None of it have been useful
for many years.
* Make it possible to specify the initctl path as a compile time
define INIT_FIFO.
* Use narrowly scoped file descriptor for handling opened TTY in
spawn(). Patch from Michał Kulling.
* Check exit code from dup() in spawn() and log error if it fail.
Patch from Michał Kulling.

INIT_CMD_CHANGECONS was introduced. Based on feedback and patch
from Bill Nottingham.
* Adjust makefile to make sure the install directories are created
before files are copied into them.
* Simplify build rules, based on patch from Mike Frysinger and Gentoo.
* Fix minor bug in optimizing of argument parsing. Based on
report from jakemus on freshmeat.
* Add casts to get rid of compiler warning about signed/unsigned issues.
* Change tty handling in init to make sure the UTF-8 flag is not cleared
on boot. Patch from Samuel Thibault.
* Add Makefile in toplevel directory.
* Print usage information when shutdown is used by non-root user.
Patch from Mike Frysinger and Gentoo.
* Sync shutdown manual page and usage information. Patch from Mike
Frysinger and Gentoo.
* Fix race condition in utmp writing. Patch from Gil Kloepfer via
Mike Frysinger and Gentoo.
* Rewrite findtty() in bootlogd to recursively search /dev/ for the
correct device, to handle terminal devices for example in /dev/pty/.
Patch from Debian.
* Make sure bootlogd findpty() returns an error value when it fails to
find a usable pty. Patch from Rob Leslie via Debian.
* Make sure bootlogd fflush() every line, even if asked not to flush
to disk using fdatasync(). Patch from Scott Gifford via Debian.
* Add compatibility code to handle old path "/etc/powerstatus" for a
while.
* Incude definition for MNT_DETACH which is missing in older GNU libc
headers.
* Do not strip binaries before installing them, to make it easier to
get binaries with debug information installed.
[ Werner Fink ]
* Add the comment from Andrea Arcangeli about the correct
place of setting the default childhandler within spawn().
* Make sure that newline is printed out for last(1) even
if an utmp record entry is truncated.
* Check if utmp not only exists but also is writable and delay
writing out of the utmp runlevel record if utmp is not writable.
* Be able to find libcrypt also on 64 bit based architectures.
* Add option -w to the last command to display the full user and
domain names in the output. Patch from Petr Lautrbach.
* Add a manual page for utmpdump as this tool is sometimes
very useful even if not intended for normal use.
* Use paths.h macros for wall
* Change path "/etc/powerstatus" to "/var/run/powerstatus"
* Detected also removable block devices at halt/reboot to be able
to flush data and send them the ATA standby command. This should
avoid data loss on USB sticks and other removable block devices.
* Flush block devices on halt/reboot if not done by the kernel.
* Set SHELL to /bin/sh in the environmant of shutdown.
* Retry to write out shutdown messages if interrupted.
* pidof/killall5 - make omit pid list a dynamic one.
* pidof - provide '-n' to skip stat(2) syscall on network based FS.
* init - avoid compiler warnings
* init - initialize console by using the macros from ttydefaults.h
* init - add the possiblity to ignore further interrupts from keyboard
* init - add the possiblity to set sane terminal line settings
* sulogin - add the possibility to reset the terminal io
* Fix some minor problems
* init - enable is_selinux_enabled() to detect selinuxfs
* Add fix for Debian bug #536574 -- Can be enabled by -DACCTON_OFF
* Add helper program fstab-decode to make it easier to handle
/etc/mtab content. Patch by Miloslav Trmac and Fedora.
* Add fix for Debian bug #335023 - Make sure TERM is set on FreeBSD.
* Add fix for Debian bug #374038 - Make it clear that shutdown -c can
only cancel a waiting shutdown, not an active one.
* Add note to pidof manual page about the use of readlink(2). Patch by
Bill Nottingham and Fedora.
* Add PAM patch contrib/notify-pam-dead.patch based on Debian bug
#68621, which will add PAM support for programs spawned by init on
the console like sulogin. Based on patch by Topi Miettinen. This
patch is not applied by default yet while we review its
usefullness. It is only helpful for session handling, as sulogin
do not use and will not use a PAM conv() function. The current
sulogin is able to handle DES as well as MD5, SHA, and Blowfish
encrypted passwords due using getpwnam(3).
* Move utmp/wtmp before the execvp() in spawn() to be sure to
use the correct pid even on a controlling tty
* Remaining problem is that the pid of the second fork() for
getting a controlling tty isn't that reported by spawn()
* Re-enable writting utmp/wtmp for boot scripts
* Extend sulogin to support additional encryption algorithms
* Re-enable maintenance message of sulogin
* Enable the sulogin fallback password check to handle MD5, SHA, and
Blowfish encrypted passwords in case of getpwnam(3) fails.
* sulogin picking the SELinux context was broken. Patch by Daniel Walsh

Patch from Debian and Goswin von Brederlow with changes by Kel
Modderman.
* Change shutdown to only accept flags -H and -P with the -h flag,
and document this requirement in the manual page.
* Change reboot/halt to work properly when used as a login shell.
Patch by Dale R. Worley and Fedora.
* Let sulogin fall back to the staticly linked /bin/sash if both roots

* Fixed up bootlogd to read /proc/cmdline. Also keep an internal
linebuffer to process \r, \t and ^H. It is becoming useable.
* Applied trivial OWL patches
* Block signals in syslog(), since syslog() is not re-entrant
(James Olin Oden <joden@malachi.lee.k12.nc.us>, redhat bug #97534)
* Minor adjustements so that sysvinit compiles on the Hurd

* Changed initreq.h to be more flexible and forwards-compatible.
* You can now through /dev/initctl set environment variables in
init that will be inherited by its children. For now, only
variables prefixed with INIT_ can be set and the maximum is
16 variables. There's also a length limit due to the size
of struct init_request, so it should be safe from abuse.
* Option -P and -H to shutdown set INIT_HALT=POWERDOWN and
INIT_HALT=HALT as environment variables as described above
* Add "mountpoint" utility.
* Slightly better algorithm in killall5.c:pidof()
* Added some patches from fedora-core (halt-usage, last -t,
sulogin-message, user-console)

and waitpid(2) return code. In certain circumstances, this leads to
TIOCSCTTY with wrong file descriptor (Vladimir N. Oleynik).

* More error checking in all wait() calling code (Dmitry V. Levin).
* Fix argv[] initialization in spawn() (Dmitry V. Levin).

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

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

'U' flag added to telinit. It forces init to re-exec itself
(passing its state through exec, certainly).
May be useful for smoother (heh) upgrades.
24 Feb 1998, AV:

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

- added support for serial console.
- updated Propaganda, manpages.
- added shutdown access control.
2.4 24-May-93
- Send out the official version into the world as
SysVinit-2.4.tar.z.
2.4g 15-May-93

now "ctrlaltdel" instead of "power{wait,fail}".
2.4a 22-Apr-93
- Fixed last to reckognize BSD style wtmp logging.
- Changed init to write wtmp records that are
SysV compliant but are also reckognized by the
BSD last. Added a '+' option to the 'process'
field of inittab, for getties that want to do
their own utmp/wtmp housekeeping (kludge!).
- Now accepts a runlevel on the command line,
and reckognizes the 'auto' argument. (Sets the
environment variable AUTOBOOT to YES)

2.2 02-Mar-93
- Made wait()'s asynchronous
- Changed whole thing to one big state machine
- Now using 'pseudo levels' # & * for SYSINIT & BOOT
- Added a new type of 'action', called leave. This
process will be executed when the system goes from a
runlevel specified in it's runlevel field to a
level that's not. Nice to bring down NFS and the like.
2.1 28-Jan-93
- Fixed a bug with 'boot' and 'once'.
- Check 'initdefault' for validity.
- Reckognizes "single" as command line argument.
- Retries execvp with 'sh -c exec ..' if command
is a shell script. (shouldn't execvp do this?)
- Added patches to use syslog if defined.
2.0 08-Dec-92
- Rewrote the code totally, so started with a new
version number.
- Dropped Minix support, this code now is Linux - specific.
- With TEST switch on, this init & telinit can
run standalone for test purposes.
1.3, 05-Jul-92
- Got a 386, so installed Linux. Added 'soft' reboot
to be default under linux. Fixed some typos.
1.2, 16-Jun-92
- Bugreport from Michael Haardt ; removed deadlock
and added 'waitpid' instead of 'wait' for SYSV.
1.1, 30-Apr-92
- Read manual wrong: there is no 'action' field called
process, but all entries are of type process. Every
'process' get exec'ed by /bin/sh -c 'exec command'.
- Rapidly respawning processes are caught in the act.
- _SYSV support is really Linux support,
done by poe@daimi.aau.dk on 25-Mar-92.
1.0, 01-Feb-92
- Initial version, very primitive for the Minix
operating system. Required some mods. to the
kernel.
