Yeah I saw this, but a simple pid check here is easy enough. Why you
must insist on enumerating everything in /etc/rc.d or
/usr/local/etc/rc.d/ makes no sense as not everything is a long
standing process.
You should know the services running on a machine and should have
targeted checks for them. That's my position anyways.

Yeah, I get all this. I personally think the word service is misused
here, but that's another topic for another day.

And that may in fact be the way.
