38#
39# DESCRIPTION:
40# Verify that rollbacks are with respect to the latest snapshot.
41#
42# STRATEGY:
43# 1. Empty a file system
44# 2. Populate the file system
45# 3. Take a snapshot of the file system
46# 4. Add new files to the file system
47# 5. Take a snapshot
48# 6. Remove the original files
49# 7. Perform a rollback
50# 8. Verify the latest snapshot and file system agree
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2005-07-04)
