Ddevpts.txt5 All mounts of the devpts filesystem now create a /dev/pts/ptmx node
8 To retain backwards compatibility the a ptmx device node (aka any node
10 of devpts under the name "pts" in the same directory as the ptmx device
13 As an option instead of placing a /dev/ptmx device node at /dev/ptmx
14 it is possible to place a symlink to /dev/pts/ptmx at /dev/ptmx or
15 to bind mount /dev/ptx/ptmx to /dev/ptmx. If you opt for using
17 the ptmxmode=0666, or chmod 0666 /dev/pts/ptmx should be called.
