  25 # DESCRIPTION:
  26 #       'zfs destroy -R <snapshot>' can destroy all the child
  27 #        snapshots and preserves all the nested datasetss.
  28 #
  29 # STRATEGY:
  30 #       1. Create nested datasets in the storage pool.
  31 #       2. Create recursive snapshots for all the nested datasets.
  32 #       3. Verify when snapshots are destroyed recursively, all
  33 #          the nested datasets still exist.
