| # DESCRIPTION: |
| # 'zfs promote' can deal with multi-point snapshots. |
| # |
| # STRATEGY: |
| # 1. Create multiple snapshots and a clone to a middle point snapshot |
| # 2. Promote the clone filesystem |
| # 3. Verify the origin filesystem and promoted filesystem include |
| # correct datasets separated by the clone point. |
| # |
