Ok, well, more like:

- openpty() will still use legacy pty devices, if they exist, but will prefer /dev/ptm.
- posix_openpt() only works with /dev/ptm.
- The new MAKEDEV that's installed by the install script does not make legacy pty devices for "MAKEDEV all".

Seems like the best course of action is to have the install script put a ptyfs entry in the generated /etc/fstab.
