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.
