servers often store their (main) process id in a "pid" file, and create a
(empty) lock file (by just touching it). if the startup script is called
twice, the lock file prevents the server to be lauched twice. when the
shutdown script is called, it removes the lock file, and usually gets the
server's pid from the pid file, then sends that process a kill signal.
in your case i'm not sure this is necessary at all : just do a "killall
-YOURSIGNAL userprocessname" in the shutdown script, and it should be enough.
