1.0, 01-Feb-92
- Initial version, very primitive for the Minix
  operating system. Required some mods. to the
  kernel.

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.

1.2, 16-Jun-92
- Bugreport from Michael Haardt ; removed deadlock
  and added 'waitpid' instead of 'wait' for SYSV.

1.3, 05-Jul-92
- Got a 386, so installed Linux. Added 'soft' reboot
  to be default under linux. Fixed some typos.

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.

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.

2.2 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.

2.3 24-Mar-93
- Ripped out the 'leave' action. To difficult, and
  unneeded.
- Going single user now kills _all_ processes.
- Added '-t secs' option to all commands.
- This version is stable enough to post.

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)

2.4g 15-May-93
- Changed init to really catch SIGPWR 'cause we
  hooked up an UPS to the Linux machine. The
  keyword for catching the TreeFingerSalute is
  now "ctrlaltdel" instead of "power{wait,fail}".

2.4  24-May-93
- Send out the official version into the world as
  SysVinit-2.4.tar.z.

2.50  14-Feb-1994
- Ignores unknown command line arguments.
- Modelled more after the "real" sysVinit
- 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).
- runlevel 0 = halt, 1 = single user, 6 = reboot.
- added support for serial console.
- updated Propaganda, manpages.
- added shutdown access control.

2.52 30-Aug-1994
- Added `powerfailnow' keyword, for when UPS battery is low.
- Updated `last'.
- Fixed utmp handling (wrt. CLEAN_UTMP)
TODO:

* update powerd
* remote SIGPWR broadcast? in powerd? (with priv. port)
* remote shutdown

2.53 10-Oct-1994
