Seems reasonable.  Question from my own "questions to be asked about glusterfs" pile:  Paths.  I notice that glusterd requires quite a few path not in the standard hierarchy for /usr/local (or any value of ${prefix}) that will cause it to simply fall over upon first invocation.  To wit:

/var/lib/glusterd (nothing in FreeBSD uses /var/lib at all - /var/db, /var/run and /var/tmp are more canonical locations, depending on what you [the service] are trying to do).

In fact, ${prefix}/var seems to be generally avoided by most things in ports.  /usr/local/var/log is highly atypical, for example.

This also creates problems for us in FreeNAS since our root filesystem is read-only by default, and we simply make parts of /var (the root /var) r/w to accommodate things wanting to write into /var/log, /var/tmp/, /var/run and so on.  I would hope that the port could also be configured to run as a system component, or at least obey a more predictable ${prefix} hierarchy so that we could map things suitably r/w into the location(s) that glusterfs needs to scribble on at runtime.

I was going to write all of this up in a more exhaustive email but I got side-tracked by other projects. :)
