  36 # DESCRIPTION:
  37 #       Verify 'destroy -r' can correctly destroy a snapshot tree at any point.
  38 #
  39 # STRATEGY:
  40 # 1. Use the snapshot -r to create snapshot for top level pool
  41 # 2. Select a middle point of the snapshot tree, use destroy -r to destroy all
  42 #       snapshots beneath the point.
  43 # 3. Verify the destroy results.
