Many versions of the BIND (named) software don't ever
look at the /etc/hosts file. I know that the SR10.2
version on the Apollos certainly doesn't seem to do
so, and the Sun/OS version (without using NIS, blech!)
doesn't either.

On all of our machines, the /etc/resolv.conf file
points to the name-daemon running on the local host
*and* the /etc/named.boot runs a cache-only server
*and* the /etc/named.ca initial-cache file contains
our campus-wide name servers *and* (this is the trick)
our locally added list of host names. Even if a particular
machine can't talk to any other host, it can see its
own name-daemon, and it at least knows the names of
our other local machines from the /etc/named.ca file.

Here's our setup:


============= cut here---/etc/resolv.conf =============
mit.edu
127.0.0.1
domain mit.edu
