39# DESCRIPTION:
40#	Verify 'destroy -r' can correctly destroy a snapshot tree at any point.
41#
42# STRATEGY:
43# 1. Use the snapshot -r to create snapshot for top level pool
44# 2. Select a middle point of the snapshot tree, use destroy -r to destroy all
45#	snapshots beneath the point.
46# 3. Verify the destroy results.
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2006-06-20)
