I am no expert, but I think what I am about to say is correct.  If you
want to turn on a service during startup, you need to tell init to do it.
One way, is to enter the command you want to run (e.g. /sbin/pmud or maybe
preferably "/etc/init.d/pmud start") into the file "/etc/rc.d/rc.local".
This is the last script executed by init when entering runlevels 2 through
5.

The "real" way to do it, is to place a symbolic link into the appropriate
rc[0-6].d directory.  For example, if you want pmud to start up in
runlevel 3, type:

ln -s /etc/init.d/pmud /etc/rc3.d/S40pmud

where the "S" tells init to run "/etc/init.d/pmud start" (whereas "K"
would tell init to run "...pmud stop") and the "40" tells init when to run
it (all the scripts referred to in /etc/rc3.d are run in numerical order).

To get it to stop pmud nicely before shutting down, you could then enter
something like:

ln -s /etc/init.d/sshd /etc/rc0.d/K60pmud

Of course, if S*pmud is already in the appropriate rc*.d directory, and
pmud is not starting up, well, then that's a whole different problem...
Hope that helps.
