33#
34# DESCRIPTION:
35#	'zfs promote' can deal with multi-point snapshots.
36#
37# STRATEGY:
38#	1. Create multiple snapshots and a clone to a middle point snapshot
39#	2. Promote the clone filesystem
40#	3. Verify the origin filesystem and promoted filesystem include
41#	   correct datasets separated by the clone point.
42#
43# TESTABILITY: explicit
44#
45# TEST_AUTOMATION_LEVEL: automated
46#
47# CODING_STATUS: COMPLETED (2006-05-16)
