39# DESCRIPTION:
40# Verify that rollbacks succeed when there are nested file systems.
41#
42# STRATEGY:
43# 1) Snapshot an empty file system and rollback
44# 2) Create a file in the file system
45# 3) Rollback the file system to empty
46# 4) Create a nested file system with the same name as the file created in (2)
47# 5) Verify a rollback succeeds
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2006-01-17)
