# DESCRIPTION:
# Verify 'snapshot -r' and 'destroy -r' can correctly create and destroy
# snapshot tree respectively.
#
# STRATEGY:
# 1. Use the snapshot -r to create snapshot for top level pool
# 2. Verify the children snapshots are created correctly.
# 3. Use destroy -r to destroy the top level snapshot
# 4. Verify that all children snapshots are destroyed too.
