In a  proper RCNG script you don't parse stop/start, you override the
stop/start functions. Parsing $1 directly is how the old-style scripts
use to work, but the base system and most ports now use the RCNG
framework.

It depends, if the script is just starting a daemon then it can
simply use the default start/stop handlers, and stop/start/restart works
without any explicit handling.
