SYNTAX
/etc/rc.init n
where n is run level S, 0, 1, 2, 3, 4, 5, or 6.
DESCRIPTION
The rc.init script is normally invoked by the init(1m) program
(it can be invoked by root). rc.init executes all specified
scripts in /etc/init.d. These scripts, such as rc.errdemon,
chk.fsck, and rc.iacs are explicitly started or stopped, thus the
total result of all scripts being executed is the conditions of a
given run level, for example, run level 3.
rc.init replaces the rc command found in previous releases.
rc.init in the run level setting sequence
1. In single-user mode, a superuser wanting to put the system
in run level 3 types: init 3.
2. The init program reads the /etc/inittab file looking for all
occurrences of the argument 3 in the second field.
3. rc.init invokes rc.init.
4. rc.init uses the argument 3 as a pointer to directory
/etc/rc3.d. This directory contains links to files in
/etc/init.d that specify which scripts should be started or
stopped by rc.init for run level 3.
5. rc.init executes all scripts (which are in /etc/init.d) for
the given run level. The system is now at run level 3.
Only files beginning with K or S are executed. All K
scripts are executed first, in reverse order (K2 before K1).
Then, all S scripts are executed in normal order.
The following lines are from /etc/inittab. The last field
contains the invocation of the rc.init script. When a superuser
chooses a run level via the init command, the inittab file is
scanned until that run level is found. Then, rc.init is
executed.
