# DESCRIPTION:
# Verify 'destroy -r' can correctly destroy a snapshot tree at any point.
#
# STRATEGY:
# 1. Use the snapshot -r to create snapshot for top level pool
# 2. Select a middle point of the snapshot tree, use destroy -r to destroy all
# snapshots beneath the point.
# 3. Verify the destroy results.
