Linux.com | Debian redefines itself with new release:
Earlier versions of the Debian installer have asked questions that inexperienced users would find puzzling, such as the domain name of their workstations. The current version of the installer still asks the question, but with clear and concise help that explains what a domain name is, and adds, “If you are setting up a home network, you can make something up, but make sure you use the same domain name on all your computers.”
I’m almost tempted to give it a try on the home machine currently running ubuntu.
