the user_request.py change is just a minor unconnected nit.
So, perhaps we should have checked this earlier buuuuuut... afaict the 'status' commands only exist since earlier in 2014.  This probably needs a fallback to 'config get', so that for modern clusters we're robust and for older clusters we hope they have a fsid in ceph.conf.

This solves the mystery of why I did it the other way first time around :-)
