Oops! I used the wrong preseed hostname value in my last diff. The
correct value is get_hostname not dhcp_hostname. I've updated the patch.

I've downloaded the installation-guide package and looked for other,
similar configuration settings. It seemed like the most obvious spot was
in the debconf variable example here:
http://d-i.alioth.debian.org/manual/en.i386/apbs04.html
The attached diff puts the netcfg/enable option at the top of the list
with an explanation and left it commented out.
