+# DESCRIPTION:
+#	Verify 'zfs destroy -f' succeeds as root.
+#
+# STRATEGY:
+#	1. Create filesystem in the storage pool
+#	2. Set mountpoint for the filesystem and make it busy
+#	3. Verify that 'zfs destroy' fails to destroy the filesystem
+#	4. Verify 'zfs destroy -f' succeeds to destroy the filesystem.
