PS undestands ptyfs, but it looks the name in devdb which contains both
the old ptys and the new ptys. Since the lookup is done by major/minor
number, both will match (they are aliases of each other; they refer to
the same device). If you remove /dev/pty?? and /dev/tty?? [the
pty's only] it will show pts/X.
