} That confuses me - If I rename it with a "K", isn't the linked script

The "S" scripts in /etc/rc2.d/ are run with the argument "start".
The "K" scripts in /etc/rc2.d/ are run with the argument "stop".
example:  S40foo would run "/etc/init.d/foo start"
K40foo would run "/etc/init.d/foo stop".


I usually just delete the symbolic link if I don't want it.
If you are not switching between different run levels the
"K" usually isn't needed.

With Redhat/Fedora run level 3 is console and 5 is X, so I
sometimes switch between 5 and 3.  Any K scripts will run at
this time to kill off X and other unwanted things.
