| # DESCRIPTION: |
| # 'zfs promote' can promote a clone filesystem to no longer be dependent |
| # on its "origin" snapshot. |
| # |
| # STRATEGY: |
| # 1. Create a snapshot and a clone of the snapshot |
| # 2. Promote the clone filesystem |
| # 3. Verify the promoted filesystem become independent |
| # |
