He wants to restore the real LV to the state it was in at the time one of the snapshots was taken.
Nah :) I want to sanp a volume, mount the snap, do my `stuff`, if I like it, I can merge into the primary copy and continue or dump the snap and go back...
That would be so very usefull! I know I can dd out the snap but that so not elegant (and slow)!
