33#
34# DESCRIPTION:
35#	'zfs promote' can promote a clone filesystem to no longer be dependent
36#	on its "origin" snapshot.
37#
38# STRATEGY:
39#	1. Create a snapshot and a clone of the snapshot
40#	2. Promote the clone filesystem
41#	3. Verify the promoted filesystem become independent
42#
43# TESTABILITY: explicit
44#
45# TEST_AUTOMATION_LEVEL: automated
46#
47# CODING_STATUS: COMPLETED (2006-05-16)
