# 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.
