# ID: zfs_acl_chmod_rwx_001_pos
#
# DESCRIPTION:
#	chmod A{+|-|=} have the correct behaviour to the ACL list. 	
#
# STRATEGY:
#	1. loop check root and non-root users
#	2. chmod file or dir with specified options
#	3. get ACE after behaviours of chmod
#	4. compare specified ACE and excpect ACE
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-09-30)
