# ID: zfs_list_007_pos
#
# DESCRIPTION:
#	'zfs list -d <n>' should get expected output.
#
# STRATEGY:
#	1. 'zfs list -d <n>' to get the output.
#	2. 'zfs list -r|egrep' to get the expected output.
#	3. Compare the two outputs, they shoud be same.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2009-05-25)
