Not sure if the above steps are actually required. Actually, neither
matter. I duplicated your steps anyway, and was greeted with the same
messages.
However,

I believe the above steps are wrong, looking at /dev/MAKEDEV:
pty*)
class=`expr $i : 'pty\(.*\)'`
case $class in
0) offset=0 name=p;;
1) offset=32 name=q;;
2) offset=64 name=r;;
3) offset=96 name=s;;
interestingly enough the command "./MAKEDEV pty3" will create (as
indicated) heh.. I was assuming too much, something is screwy here.
*confused*
it actually only created 64 terminals. Added the line:
4) offset=192 name=t;;
~# ./MAKEDEV pty4 && kill -HUP 1
interesting, now I have 96, but can only use 64. Reboot..
Anyone care to take over?
