# ID: zfs_destroy_007_neg
#
# DESCRIPTION:
#	'zpool destroy' failed if this filesystem is namespace-parent
#	of origin. 
#
# STRATEGY:
#	1. Create pool, fs and snapshot.
#	2. Create a namespace-parent of origin clone.
#	3. Promote this clone
#	4. Verify the original fs can not be destroyed.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-07-18)
