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