The cow begins life as a real LV.
There is no way to distinguish it from other LVs.

Changing that means changing the "create a snapshot" process into a single
LVM2 metadata transaction (or a pair of related transactions).  Currently it's
two independent transactions - creating a new, empty LV; creating a snapshot
using that LV.  Doing that would allow us to back out the change properly if
it's aborted too.
