39# DESCRIPTION:
40#	Verify 'snapshot -r' can create snapshot for promoted clone, and vice
41#	versa, a clone filesystem from the snapshot created by 'snapshot -r'
42#	can be correctly promoted.
43#
44# STRATEGY:
45#	1. Create a dataset tree
46#	2. snapshot a filesystem and clone the snapshot
47#	3. promote the clone
48#	4. snapshot -r the dataset tree
49#	5. verify that the snapshot of cloned filesystem is created correctly
50#	6. clone a snapshot from the snapshot tree
51#	7. promote the clone
52#	8. verify that the clone is promoted correctly.
53#
54# TESTABILITY: explicit
55#
56# TEST_AUTOMATION_LEVEL: automated
57#
58# CODING_STATUS: COMPLETED (2006-06-20)
