 - sockets, devs, doors, the usual stuff: I interpreted the original problem 
sub-item spec as getting a byte-for-byte copy of the lfs partition(s) as-is, 
and then restoring them. If instead it's loosened to not bothering about some 
items/aspects and allowing/assuming their re-creation automatically, then yeah 
fine: but I wouldn't do backups of full-system snapshots that way.
