41# DESCRIPTION:
42# Verify that rollbacks succeed when there are nested file systems.
43#
44# STRATEGY:
45# 1) Snapshot an empty file system and rollback
46# 2) Create a file in the file system
47# 3) Rollback the file system to empty
48# 4) Create a nested file system with the same name as the file created in (2)
49# 5) Verify a rollback succeeds
50#
51# TESTABILITY: explicit
52#
53# TEST_AUTOMATION_LEVEL: automated
54#
55# CODING_STATUS: COMPLETED (2006-01-17)
