- #
- # 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.
- #
- # TESTABILITY: explicit
- #
- # TEST_AUTOMATION_LEVEL: automated
- #
- # CODING_STATUS: COMPLETED (2006-03-02)
