correct name in scripts when administrating large installations.
Some unix-types do not handle FQDN as hostname, but luckily they are

I'd say etherconf do the right thing there. But etherconf is
dangerous for other reasons. It might reconfigure your network when
upgrading, based on the content in the debconf database.
