+# DESCRIPTION:
+#	'zfs destroy -r|-rf|-R|-Rf <fs|ctr|vol|snap>' should recursively destroy
+#	all children and clones based on options.
+#
+# STRATEGY:
+#	1. Create test environment according to options. There are three test
+#	models can be created. Only ctr, fs & vol; with snap; with clone.
+#	2. According to option, make the dataset busy or not.
+#	3. Run 'zfs destroy [-rRf] <dataset>'
+#	4. According to dataset and option, check if get the expected results.
+#
+
+verify_runnable "both"
+
+#
+# According to parameters, 1st, create suitable testing environment. 2nd,
+# run 'zfs destroy $opt <dataset>'. 3rd, check the system status.
+#
+# $1 option of 'zfs destroy'
+# $2 dataset will be destroied.
