What is the purpose? Does it allow snapshots that share space like in
Zumastor? Do all the thin LVs start with a preconfigured image which
can then be modified? (Can be done with snapshots - updating the
snapshots, but not the master, is efficient. Presumably this way all
the snapshots can share space.)
