This should be ok, but it would not cover all use cases. For example, a
thin snapshot taken, and removed, for backup purpose would repeatedly
trigger the warning.
So, while more "intelligence" on when printing the warning on lvm side
is welcomed, I really advocate for a simple command line option (or
lvm.conf parameter) to skip the warning.

Sure, I was only describing a possible case where the warning is
"redundant" (ie: because the admin know the snapshot will be short-lived).
Thanks.
