We can't, really, because it will open the global ptmx. This is an
unfortunate side effect of the backwards-compatibility code.
This is also why I don't like the bind mount; the symlink option has the
nice property that f*ckups are more obvious.
The non-legacy option should be as follows, IMNSHO:
- ALL mounts of devpts use -o newinstance;
- /dev/ptmx -> pts/ptmx symlink.
