Removed old LSM file.
Added .gitignore files to avoid git tracking object files. Removed old start-stop-daemon from contrib directory.

README for SysV init
|
||||
====================
|
||||
|
||||
SysV init is a classic initilization program (PID 1) for GNU/Linux and
|
||||
other UNIX/POSIX systems. It is designed to be small, simple and to
|
||||
stay out of the way.
|
||||
|
||||
Init is the parent (or grandparent) of all other processes on the
|
||||
system. It kicks off the starting of other system services and
|
||||
can act as a parent process to services which no longer have an
|
||||
active parent process.
|
||||
|
||||
SysV init uses the concept of runlevels. A runlevel is a configuration of the
|
||||
system which allows only a selected group of processes to exist.
|
||||
The processes spawned by init for each of these runlevels are defined in the
|
||||
/etc/inittab file. Init can be in one of eight runlevels. The runlevel is
|
||||
changed by the administrator running the telinit command which selects
|
||||
which runlevel we want to use.
|
||||
|
||||
More information on init, runlevels and switching between them can be found
|
||||
in the init manual page. (See "man init".)

Start-stop-daemon is the program that is used by the Debian style init
|
||||
scripts to start and stop services. This program is part of the "dpkg"
|
||||
package by Ian Jackson. However there is also a seperate C version (the
|
||||
original is in Perl) available written by Marek Michalkiewicz. I am including
|
||||
it for your convinience.
|
||||
|
||||
Note that the latest Debian dpkg packages (4.0.18 and later) contain
|
||||
a much improved update-rc.d. This code is almost a year old.
|
||||
|
||||
The original announcement follows:

||||
Subject: Fast start-stop-daemon in C
|
||||
To: debian-devel@lists.debian.org
|
||||
Date: Thu, 6 Jun 1996 05:24:18 +0200 (MET DST)
|
||||
|
||||
Some time ago I wrote a faster C replacement for the start-stop-daemon
|
||||
perl script. I use it for some time now (the most recent changes were
|
||||
just a nicer help screen; the code is quite stable).
|
||||
|
||||
This makes the system boot faster (especially on low end machines),
|
||||
and important system startup scripts no longer depend on another big
|
||||
package (perl). Maybe in the future we can get to the point where
|
||||
a minimal system will work without perl installed at all (packages
|
||||
which need it in {pre,post}{inst,rm} scripts would depend on perl).
|
||||
|
||||
The only problem known so far to me is that I have to reinstall this
|
||||
program after every dpkg upgrade which overwrites it with that nice
|
||||
slooow perl script :-).
|
||||
|
||||
Just compile this program and drop the binary in /usr/sbin instead
|
||||
of the original /usr/sbin/start-stop-daemon perl script (make a copy
|
||||
of it first, just in case). See below for source code. I placed it
|
||||
in the public domain, but if it has to be GPL-ed to be included in
|
||||
dpkg, just tell me. Including it in dpkg would close Bug#1670.
|
||||
|
||||
I am posting it here so that it can be tested by more people than
|
||||
just me. Bugs are unlikely though.
|
||||
|
||||
Have fun,
|
||||
|
||||
Marek
