The zfs man page reads:
File system snapshots can be accessed under the ".zfs/snapshot" direc-
tory in the root of the file system. Snapshots are automatically
mounted on demand and may be unmounted at regular intervals. The visi-
bility of the ".zfs" directory can be controlled by the "snapdir" prop-
erty.
"may be unmounted at regular intervals" <-- what about this? Do I have to create a periodic script that'll unmount snapshots? And if so, how can I make a script that'll unmount only snapshots mounted for over, say, 1 hour?
