# 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.
