When the kern.pts.enable sysctl is set to '1', pseudo-ttys are created
with device name /dev/pts/${NUMBER}. With some kernel fixes from kib
this appears to now be stable and the kernel side is ready for a
possible change of default. However, the new device naming confuses
some userland utilities. For example:
pointyhat# write simon
write: /dev/398: No such file or directory
simon was logged in on /dev/pts/398.
killall -t also fails to parse the new device format:
bento# ps -t pts/187
PID TT STAT TIME COMMAND
67734 187 Ss 0:00.04 /bin/csh
72599 187 R+ 0:00.00 ps -t pts/187
bento# killall -t pts/187
killall: stat(/dev/ttypts/187): No such file or directory
It would also be useful if ps -t recognized a numeric argument as
magic and converted it to add the pts/. It already appears to do the
converse when displaying the TTY, as you can see above.
There are probably other utilities also affected.
