For Ubuntu, it does depend at least partly on answers to the questions
at install time.

During install, there is a dialog box that asks for the host name.
Debian has a separate dialog box for the domain, but Ubuntu actually
wants the FQDN in that one box.  The install adds a line to /etc/hosts
with an IP address of 127.0.1.1, that has the FQDN and the short host
name.

The other place that may affect this is the domain entry
in /etc/resolv.conf


If you change both places, and then reboot each machine, you should have
them all in the new domain
