| # DESCRIPTION: |
| # ZFS 'snapshot_limit' is enforced when executing various actions |
| # |
| # STRATEGY: |
| # 1. Verify 'zfs snapshot' cannot exceed the snapshot_limit |
| # 2. Verify 'zfs rename' cannot move snapshots exceeding the limit |
| # 3. Verify 'zfs promote' cannot exceed the limit |
| # 4. Verify 'zfs receive' cannot exceed the limit |
| # |
