Jesse Smith 483dc777d2 Changed the way the "when" variable is used internally in shutdown.c. It starts as a NULL pointer, then might get set as a pointer to optarg, then it might get set to point to an argv parameter, then it might have a string value copied into it, over-writing the original data. We should not risk over-writing internal variables which might get used for something else (it's rude and security risk). Set up "when" as its own buffer that has data from optargs and/or argv copied into it. Minor code fixes across multiple source files to avoid buffer overflows, or uninitialized strings.		2019-01-27 15:55:08 -04:00

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".)
