- # DESCRIPTION:
- # Verify that rollbacks succeed when there are nested file systems.
- #
- # STRATEGY:
- # 1) Snapshot an empty file system and rollback
- # 2) Create a file in the file system
- # 3) Rollback the file system to empty
- # 4) Create a nested file system with the same name as the file created in (2)
- # 5) Verify a rollback succeeds
