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