To be honest, there is no difference in installing RHEL6 with a static
ip address or Ubuntu Server with DHCP enabled.

I think we need to find out first, what user base we want to point at.

The SysAdmin of a Company with Enterprise Classed Datacenter
or the guy/gal from around the corner who is testing ubuntu server?

The SysAdmin will have network security in place (if not..oh well), and
mostly is he/she not using public IP addresses, and/or they setup their
DHCPd to match the MACs of the NICs inside their servers.

I am now wondering if we really should change something. As long as I'm
thinking about the topic, I'm coming to my conclusion, that we just
should tick sshd by default during tasksel in the installer, and that's
it. For most of the admins out there, it really doesn't matter, because
they have other ways to deploy ubuntu server on their servers.
