--5vNYLRcllDrimb99 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline 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.
