  36 # DESCRIPTION:
  37 #       Verify 'snapshot -r' can create snapshot for promoted clone, and vice
  38 #       versa, a clone filesystem from the snapshot created by 'snapshot -r'
  39 #       can be correctly promoted.
  40 #
  41 # STRATEGY:
  42 #       1. Create a dataset tree
  43 #       2. snapshot a filesystem and clone the snapshot
  44 #       3. promote the clone
  45 #       4. snapshot -r the dataset tree
  46 #       5. verify that the snapshot of cloned filesystem is created correctly
  47 #       6. clone a snapshot from the snapshot tree
  48 #       7. promote the clone
  49 #       8. verify that the clone is promoted correctly.
