man update-rc.d

1. Run grep to see what your default runlevel is:
	grep initdefault /etc/inittab
   It should say:
	id:2:initdefault:
   The number after 'id' refers to your default runlevel.  Lets assume
   you are running runlevel 2 for this exercise.

2. Use update-rc.d to maintain your runlevel configuration.  Lets say you
   have a service called Samba you want removed from starting up, look in
   /etc/rc2.d:
	ls /etc/rc2.d/
   You see the following symlink there:
	S20samba
   Break down the filename:  S means start, 20 is the start order, and
   samba is the actual name of the service.  Use update-rc.d to remove
   the service by name:
	update-rc.d -f samba remove

3. OOps, i actually want samba!  Then run:
	update-rc.d samba defaults

There you have it, quick and dirty service maintenance.
