36#
37# DESCRIPTION:
38#	'zfs promote' can deal with multi-level clones.
39#
40# STRATEGY:
41#	1. Create multiple snapshots and multi-level clones
42#	2. Promote a clone filesystem
43#	3. Verify the dataset dependency relationships are correct after promotion.
44#
45# TESTABILITY: explicit
46#
47# TEST_AUTOMATION_LEVEL: automated
48#
49# CODING_STATUS: COMPLETED (2006-05-16)
