We assign a random UUID with tune2fs to snapshots
and shares created from snapshots so that they
don't conflict with the parent shares/snapshots
when both of them are being mounted.
tune2fs requires that a filesystem check be
performed "recently" before UUID assignments.
So, perform a filesystem check right away to
allow tune2fs to assign a random UUID.
