How we converted Sun 2/50s into "X terminals".
What we did was to strip down SunOS 4.0.3, removing that which isn't
needed. The process is:
1. Configure a stripped kernel (2/50 configuration supplied).
2. Edit /etc/rc and or /etc/rc.local to start up only >>essential<<
network servers (e.g. /etc/inetd).
3. Edit /etc/inetd.conf to remove most network services (sample provided).
4. Change /etc/ttytab to start up X server.
5. Configure an xdm to service the terminal.
6. Reboot the new X-terminal.
