Can't get more unambiguous than only having one label!
The word to look for here is "wither". When a device label name is
opened exclusively (like mounting a device), other labels for that
device are supposed to "wither" and disappear from view.
(My understanding of this is incomplete. Garrett Wollman sent me a very
nice explanation of how this works, which I have read but not enough
times yet.)
