41# DESCRIPTION:
42#	Verify snapshot can be created or destroy via mkdir or rm
43#	in $(get_snapdir_name).
44#
45# STRATEGY:
46#	1. Verify make directories only successfully in $(get_snapdir_name).
47#	2. Verify snapshot can be created and destroy via mkdir and remove
48#	directories in $(get_snapdir_name).
49#	3. Verify rollback to previous snapshot can succeed.
50#	4. Verify remove directory in snapdir can destroy snapshot.
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2006-10-17)
