The firstboot package has various dependencies that I don't really
want. But it could be a good model.

Given the limitations of what can actually be run during the %post
phase, I'm not sure if it is easier. There are warnings about lack of
name resolution if the system is configured for DHCP.
While it is possible for me to install a custom package before the
first reboot, mixing it in with all the CentOS packages in the install
server seems to be a really bad idea. With the potential lack of name
resolution, the other option would be to install via FTP, but that
requires hardcoding the IP address. Not a great idea either.

Good point, but how do you suggest I bootstrap it in?
