One of these days I should really sit down and understand masters and slaves and ttys and ptys and such. I'll just add it to my list of things to do. Maybe I'll get to it before my kids go off to college in ten years. :-) All I know is the permissions in the tar file don't match what I get if I remake the device entries with MAKEDEV. I also know that xterm works on dozens of platforms, including FreeBSD 2.1R. Now that doesn't mean I think xterm is perfect, or even good. In fact I think xterm is a big piece of shit. Nevertheless, it works. I'm just letting you all know about what looks like a problem. If FreeBSD is really planning on changing the default permissions of the device entries, I think it would be a good idea to fix xterm to work with the new permissions, and while you're at it submit a bug-report to the X Consortium or XFree86 with the necessary changes to xterm. -- Kaleb KEITHLEY
