This is pretty specific to HekaFS, but it would be nice if there were a way to hook into the volfile-generation process and let glusterd handle daemons and ports, instead of managing all of these related issues ourselves.  See the first part of the linked cloudfs-devel post for a more complete explanation.  In a moment, I'll post a patch implementing the generic part of this mechanism, in such a way that "vanilla" configurations will be unaffected.
