Notes about Solaris and PID files:

 - On Solaris daemons managed by SMF don't need PID files unless you
   have utilities that need to know a daemon's PID so they can signal it
   (for any purpose *other* than killing it or otherwise making it
   exit).

 - On Solaris PID files should live in /var/run, and if they really must
   be in /etc/ then it must be possible to have a symlink in /etc
   instead that points to /var/run/...
