| # DESCRIPTION: |
| # Verify snapshot can be created or destroy via mkdir or rm |
| # in .zfs/snapshot. |
| # |
| # STRATEGY: |
| # 1. Verify make directories only successfully in .zfs/snapshot. |
| # 2. Verify snapshot can be created and destroy via mkdir and remove |
| # directories in .zfs/snapshot. |
| # 3. Verify rollback to previous snapshot can succeed. |
| # 4. Verify remove directory in snapdir can destroy snapshot. |
| # |
