# DESCRIPTION:
#	Verify snapshot can be created or destroy via mkdir or rm

# STRATEGY:
#	1. Verify make directories only successfully in .zfs/snapshot.
#	2. Verify snapshot can be created and destroy via mkdir and remove
#	directories in .zfs/snapshot.
#	3. Verify rollback to previous snapshot can succeed.
#	4. Verify remove directory in snapdir can destroy snapshot.
