| # DESCRIPTION: |
| # zfs unmount should work on nested datasets |
| # |
| # STRATEGY: |
| # 1. Create a set of nested datasets |
| # 2. Unmount a nested dataset and make sure it is unmounted |
| # 3. Ensure the dataset deeper than the one above is also unmounted |
| # 4. Ensure the datasets shallower than the unmounted one is still mounted |
| # 5. Repeat from step 2 with other mountpoint values and shallower nesting |
| # |
