35# DESCRIPTION:
36#	Verify chmod have correct behaviour to directory and file when setting
37#	different inherit strategy to them.
38#
39# STRATEGY:
40#	1. Loop super user and non-super user to run the test case.
41#	2. Create basedir and a set of subdirectores and files within it.
42#	3. Separately chmod basedir with different inherite options.
43#	4. Then create nested directories and files like the following.
44#
45#                                                   _ odir4
46#                                                  |_ ofile4
47#                                         _ odir3 _|
48#                                        |_ ofile3
49#                               _ odir1 _|
50#                              |_ ofile2
51#                     basefile |
52#          chmod -->  basedir -|
53#                              |_ nfile1
54#                              |_ ndir1 _
55#                                        |_ nfile2
56#                                        |_ ndir2 _
57#                                                  |_ nfile3
