Yes I think so. The ability to specify the PID path inside of a config
file is a misfeature IMO. The person starting the daemon (OpenRC, in
this case) is the only one who needs to care about the PID file, and
having it in a config file just means that you have to change it in two
places if you ever do decide to change it. It's much simpler to ignore
the conf file (with -g pid ...) and let the init script be the source
of truth.

Very rarely someone will complain that they tried to change the PID
location in their config file and it didn't work... but if you think
about it for a second, that wouldn't have worked anyway.

Ok, no problem. I understood the checkpath but was curious about the
quality of the error message with checkconfig() vs start(). Thanks for
working on this!
