38#
39# DESCRIPTION:
40#	'zfs promote' can promote a clone filesystem to no longer be dependent
41#	on its "origin" snapshot.
42#
43# STRATEGY:
44#	1. Create a snapshot and a clone of the snapshot
45#	2. Promote the clone filesystem
46#	3. Verify the promoted filesystem become independent
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2006-05-16)
