Re: Daemon mgmt was Re: turning off /sbin/portmap
just about that ;)
when entering a runlevel, the daemon basically goes through each file in
/etc/rcx.d that starts with S and runs it like this:
S90startstuff start
note the start argument. Then when leaving it does the same thing with
the K's saying stop.
They are run in numerical order, so dependencies aren't a problem if they exist.
Also, it is legal for two scripts to have the same number. When I add
them, I usually just give them S99.
Because of that you'll see that most/all of the files in /etc/rcx.d are
symlinks to scripts in /etc/init.d/
