#
# ID: snapshot_012_pos
#
# DESCRIPTION:
#	Verify 'snapshot -r' can create snapshot for promoted clone, and vice
#	versa, a clone filesystem from the snapshot created by 'snapshot -r' 
#	can be correctly promoted.
#
# STRATEGY:
#	1. Create a dataset tree
#	2. snapshot a filesystem and clone the snapshot
#	3. promote the clone
#	4. snapshot -r the dataset tree
#	5. verify that the snapshot of cloned filesystem is created correctly
#	6. clone a snapshot from the snapshot tree
#	7. promote the clone
#	8. verify that the clone is promoted correctly.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-06-20)
