Manifest additions: add creator/swapper, pid/gid/eid metadata?
I realize not everyone might think this is necessary. I'm not even sure what I think; but it is a missing piece. For instance, I believe my openstack setup scripts only use PID/EID to construct FQDNs for hosts if the GENI/manifest way doesn't work (for whatever reason).
