You're right that Hobbit didn't anticipate this setup. The disk-RRD
naming was adopted from LARRD which uses this scheme; Hobbit just 
kept it to maintain compatibility and because I didn't expect it 
to cause any problems.

I think this is sufficiently rare that it's not really worth the
effort to arrange for some special-case handling of a "/root"
filesystem. So - at least for now - I'll leave it as-is.
