# ID: zfs_acl_chmod_inherit_001_pos
#
# DESCRIPTION:
#	Verify chmod have correct behaviour to directory and file when setting
#	different inherit strategy to them.
#	
# 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. Separately chmod basedir with different inherite options.
#	4. Then create nested directories and files like the following.
#	
#                                                   _ odir4
#                                                  |_ ofile4
#                                         _ odir3 _|
#                                        |_ ofile3
#                               _ odir1 _|
#                              |_ ofile2
#                     basefile |
#          chmod -->  basedir -| 
#                              |_ nfile1
#                              |_ ndir1 _ 
#                                        |_ nfile2
#                                        |_ ndir2 _
#                                                  |_ nfile3
#                                                  |_ ndir3
#
#	5. Verify each directories and files have the correct access control
#	   capability.
#	
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-11-15)
