Very interesting. Thanks for pointing that out. :) I have often wondered
what the K vs S was in those scripts. I discovered update-rc.d while
looking for an equivalent for Gentoo's "rc-update" application some time
ago. I didn't realize it wasn't meant to be used by the user.

BTW, sysv-rc-conf made my head explode. It makes every controller I've
used in the past look like peanuts.

Cheers!
