    I want to change context from ... below.
drwxr-xr-x  root     root     root:object_r:root_t             home3

   to ... below.
drwxr-xr-x  root     root                                                       home3

    How can I do with "chcon" command ? (delete root:object_r:root_t )
                  Best Regards,
                       Somsak.
