Is glusterd starting? I'm getting the impression that it's starting, but 
that it has no configuration. As far as I know, Gluster keeps most of 
the configuration on the brick itself, but it finds brick information in 
/var/lib/glusterd.

The last patch simply opened the firewall, and it's entirely possible 
that we need to persist this. It may be a good idea to just persist the 
entire directory from the get-go, unless we want to try to have a thread 
watching /var/lib/glusterd for relevant files, but then we're stuck 
trying to keep up with what's happening with gluster itself...
