Release Status: release

Description:
        https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=155373

        Running ">/inaccessible" as a normal user results in the error
        "No such file or directory" rather than the expected
        "Permission denied".  This is due to AFS support.

        >/inaccessible
