| H A D | devpts.rst | 11 All mounts of the devpts filesystem now create a ``/dev/pts/ptmx`` node
14 To retain backwards compatibility the a ptmx device node (aka any node
16 of devpts under the name ``pts`` in the same directory as the ptmx device
19 As an option instead of placing a ``/dev/ptmx`` device node at ``/dev/ptmx``
20 it is possible to place a symlink to ``/dev/pts/ptmx`` at ``/dev/ptmx`` or
21 to bind mount ``/dev/ptx/ptmx`` to ``/dev/ptmx``. If you opt for using
23 the ``ptmxmode=0666``, or ``chmod 0666 /dev/pts/ptmx`` should be called.
