AFAIK, a well-configured machine has /etc/hosts setup so that
gethostbyname(gothostname()) does not touch DNS, but is resolved
entirely from reading /etc/hosts. Doesn't the installer *by* *default*
set things up like that? At least, the Debian installer does.

This does not help with "badly configured situations", indeed :-|
