# DESCRIPTION:
# Verify snapshot can be created or destroy via mkdir or rm
# in .zfs/snapshot.
#
# 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.
