Ultrix 4.0 (1990) had /etc/svc.conf for controlling distributed service
lookups, and you are correct that the only options were local, yp, and
bind. Ultrix 3 (1988) had /etc/svcorder which was much more limited, only
allowing for setting the order of host lookups, but it did have support for
resolv.conf and BIND lookups (which still works!).
