In particular:

/dev/ptmx can be a symlink ptmx -> pts/ptmx, and we add a ptmx instance 
inside the devpts filesystem.  Each devpts filesystem is responsible for 
its own pool of ptys, with own numbering, etc.

This does mean that entries in /dev/pts are more than just plain device 
nodes, which they are now (you can cp -a a device node from /dev/pts 
into another filesystem and it will still "just work"), but I doubt this 
actually matters to anyone.  If anyone cares, now I guess would be a 
good time to speak up.
