This doesn'= ;t mesh with my memory. I recall building BIND from source and having to re= build network programs (e.g. on 4.3 on the RT or VAXen) to pick up the new = version of libresolv.a, and hacking the resolver library into libc.so on Su= ns. I remember using resolv.conf fairly early on, but my memory is that nss= witch.conf came later (Solaris 2.x era?). Ultrix did have a configuration f= ile for where to do host lookups, but I think the set of sources was fixed:= files, NIS or DNS.

I alw= ays assumed that nsswitch came much later than DNS, based just on the fact = that Linux glibc on older systems still ships an /etc/host.conf "resol= ver configuration file" that has such parameters as "order hosts,= bind,nis" (although they're inoperative).
