31# DESCRIPTION:
32#	Verify chmod have correct behaviour to directory and file when setting
33#	different inherit strategy to them.
34#
35# STRATEGY:
36#	1. Loop super user and non-super user to run the test case.
37#	2. Create basedir and a set of subdirectores and files within it.
38#	3. Separately chmod basedir with different inherite options.
39#	4. Then create nested directories and files like the following.
40#
41#                                                   _ odir4
42#                                                  |_ ofile4
43#                                         _ odir3 _|
44#                                        |_ ofile3
45#                               _ odir1 _|
46#                              |_ ofile2
47#                     basefile |
48#          chmod -->  basedir -|
49#                              |_ nfile1
50#                              |_ ndir1 _
51#                                        |_ nfile2
52#                                        |_ ndir2 _
53#                                                  |_ nfile3
54#                                                  |_ ndir3
