Alain Knaff pointed out an easy fix for this in
https://bugs.launchpad.net/ubuntu/+source/netcfg/+bug/160778:

  [ Alain Knaff ]
  * If we detect that the user entered a fully-qualified domain name as the
    hostname, then remove the domain part from the hostname as well as
    copying it to netcfg/get_domain (closes: #401220).

I haven't tested this yet, but I can't find any fault in the logic.
