man init:

/sbin/telinit [ -t SECONDS ] [ 0123456sSQqabcUu ]
RUNLEVELS
A runlevel is a software 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: 0-6 and S (a.k.a. s). The
runlevel
Runlevels S, 0, 1, and 6 are reserved. Runlevel S is used to initial-
ize the system on boot. When starting runlevel S (on boot) or
runlevel
1 (switching from a multi-user runlevel) the system is entering
``single-user mode'', after which the current runlevel is S. Runlevel
0 is used to halt the system; runlevel 6 is used to reboot the system.
After booting through S the system automatically enters one of the
multi-user runlevels 2 through 5, unless there was some problem that
needs to be fixed by the administrator in single-user mode. Normally
after entering single-user mode the administrator performs maintenance
and then reboots the system.
