Indeed it seems like it's never worked.  The issue is: how do we know
the pid-file if the user is using the raw config.  Sounds like we need a
service, in that case, that works without pid-file.

Cool, I'd be happy to review.  Thanks for this email.  It's a long time
I haven't been using Prosody and unfortunately this Guile wrapper is a
maintenance burden.  Even more so now that XMPP is less and less used.

I wonder if it would be better to just support a minimal raw config.
