    On Debian based systems /dev/ptmx is 0666 root.root. But the gid of tty
    is already supplied for devpts.

    Hmm. Several possibilities:
    - Change the filesysteme name and the old name remains usable with
    /dev/ptmx.
    Problem: You could mount the filesystem with the old name within a
    container.
    - Make the first mounted one special.
    Problem: Will not survive a umount/mount cycle. But this would be not
    the case anyway.

    But you are sure, none of them is a pretty solution.
