# DESCRIPTION:
#   Verify chmod have correct behaviour to directory and file when
#   filesystem has the different aclinherit setting
#
# 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,
#       combine with the variable setting of aclinherit:
#       "discard", "noallow", "secure" or "passthrough".
#   4. Then create nested directories and files like the following.
#
#                     ofile
#                     odir
#          chmod -->  basedir -|
#                              |_ nfile1
#                              |_ ndir1 _
#                                        |_ nfile2
#                                        |_ ndir2 _
#                                                  |_ nfile3
#                                                  |_ ndir3
#
#   5. Verify each directories and files have the correct access control
#      capability.
