For Debian prior to Squeeze, the update-rc.d
command can be used to dis-/en-able boot/shutdown scripts in the various run levels. man update-rc.d
explains but it is not exactly introductory level!
For Squeeze, it is the insserv
command instead of update-rc.d
I could not find a tutorial or HOWTO for insserv
Some of the daemons are dis-/en-abled by variables set in the /etc/defaults directory. This is described in the Debian Reference Manual
BTW adding a second post to the thread on another topic is probably not the best way to get answers. Firstly it takes your thread off the "zero reply list" so it is not automatically "bumped" into the new posts and secondly it will get confusing if people start to answer both questions in the same thread. You could start a new thread with the content of your second post, and then edit the second post, removing the content and giving a link to your new thread.
