I was at udel until 1988 and we started dealing with dns ca. 1986, and the shared library stuff I dealt with in sunos came later. Was there really an nsswitch.conf before 1988 that used shared libraries? When did you first see nsswitch.conf? I first saw the shared libraries with sunos 4.0 when I moved to super.org in 1988. I always thought it started with them on Unix anyway. In any event, dns was in some ways a big improvement in life. We were ftp'ing the 256KiB host file from prep frequently (along with many) and the load on prep, evidently, was getting high. And a linear search of a 256KiB hosts file for every single gethostbyname was getting ... noticeable. I assume this is part of why stayopen was an option in the library. People got upset about some things with DNS: "it's called prep, not prep.ai.mit.edu, what is this nonsense?" But we adjusted.
