What is the exact diff between init 1,init S and init s


Hi fnds,
What is the diff between init 1,init S and init s in RHEL
i thought that they are equal but in "init 1" i know it is single user mode and we cant have network capabilities but when we use "init S or init s, we are able to have all the networking features like NFS,NIS..etc.
as i thought if they are equal how can we have the n/w features in
"init S" or "init s"
thank you in advance

man init
Quote:
Runlevel S is used to initialize the system on boot. When starting runlevel S (on boot) or runlevel 1 (switching from a multi-user run‐level) the system is entering ‘‘single-user mode’’, after which the current runlevel is S.
Runlevels S and s are the same. Internally they are aliases for the same runlevel.
As for why you still have network when you go from runlevel 2-5 to 1, there's probably no KXXnetwork* in rc1.d, so networking isn't killed. Boot directly into single-user mode and you won't have it.
