# ID: zfs_acl_chmod_inherit_004_pos
#
# DESCRIPTION:
#	Verify aclinherit=passthrough-x will inherit the 'x' bits while mode request.
#	
# STRATEGY:
#	1. Loop super user and non-super user to run the test case.
#	2. Create basedir and a set of subdirectores and files within it.
#	3. Set aclinherit=passthrough-x
#	4. Verify only passthrough-x will inherit the 'x' bits while mode request.
#	
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2009-04-29)
