ibsim is unlikely to be used by end users or system administrators in a
normal startup environment.  I doubt it needs to be accounted for in the
init script.  Most users simply don't even know enough about ibsim to be
able to use it at all.

The stop action in the script should handle cleanup for you.  If it's
called, and a pid file exists, but the pid is not running, it should
remove the pid file and the subsystem lock file so that a clean start works.
