If you only put the domain name into that section of the installer then
it's stored in /etc/network/interfaces. But clearly it is being
stored elsewhere - if you comment out that dns search line and then:-
$ hostname -d
man getdomainname give some clues.

As previously noted - www is a subdomain, not a host. "host" queries the
DNS, which has it's own set of rules for guessing the answer.

I can't reproduce your results. Perhaps that points to the DNS server setup?

So am I, but I don't understand your question (it seems ambiguous) :)

Not trying to be obtuse but...
Where is it *stored*? Or where is it *used*?
The former I'm not certain of (see comment on editing interfaces) and
the latter is a list I don't know the full extent of.

Yes (AFAIK). But that's used for a lot of things (using getdomainname).
