  24 # DESCRIPTION:
  25 #       zfs unmount should work on nested datasets
  26 #
  27 # STRATEGY:
  28 #       1. Create a set of nested datasets
  29 #       2. Unmount a nested dataset and make sure it is unmounted
  30 #       3. Ensure the dataset deeper than the one above is also unmounted
  31 #       4. Ensure the datasets shallower than the unmounted one is still mounted
  32 #       5. Repeat from step 2 with other mountpoint values and shallower nesting
