Is this a laptop? If it's a server, or a workstation, the opinion around
here is NetworkManager MUST DIE.... If you're hardwired, you don't need
it, ever - network is still there, and doesn't screw around with your
settings.

Here's another question: you're building it via kickstart - are you
getting the hostname via dhcp?

We've got a perl script to create a ks file dynamically, depending on what
option we want (server, desktop, etc), and we get the name via dhcp, and
put that in.
