32# ID: rollback_001_pos
33#
34# DESCRIPTION:
35# Populate a file system and take a snapshot. Add some more files to the
36# file system and rollback to the last snapshot. Verify no post snapshot
37# file exist.
38#
39# STRATEGY:
40# 1. Empty a file system
41# 2. Populate the file system
42# 3. Take a snapshot of the file system
43# 4. Add new files to the file system
44# 5. Perform a rollback
45# 6. Verify the snapshot and file system agree
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING_STATUS: COMPLETED (2005-07-04)
