The daemon is responsible for creating the pidfile.

I don't recall the full details, but rcng needs to know the pid of a
daemon to shut it down, but it's possible that the daemon has died and
that pid has been reassigned to something else. So before it shuts the
daemon down it checks the command field in the ps output.

command_interpreter is a part of reconstructing that command field.
I'm not sure, but  I don't think it plays a part in starting the
daemon.
