38#
39# DESCRIPTION:
40# Populate a file system and take a snapshot. Add some more files to the
41# file system and rollback to the last snapshot. Verify no post snapshot
42# file exist.
43#
44# STRATEGY:
45# 1. Empty a file system
46# 2. Populate the file system
47# 3. Take a snapshot of the file system
48# 4. Add new files to the file system
49# 5. Perform a rollback
50# 6. Verify the snapshot and file system agree
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2005-07-04)
