Fix that by never allowing pexp to become empty.

its _flags in rc.conf(8).
When the rc.d(8) system starts a daemon, it will record its pexp under
/var/run/rc.d/rcscriptname and use that to interact with it (errors in
creating /var/run/rc.d or missing pexp file are non fatal, the framework
will just fallback to what it currently does).
deraadt@ doesn't mind a long as it doesn't come in the way of people
manually managing their daemons.
