Kernel RPM Question

[linuxproject at aws-sj.com]

Hi,
   First off I would like to say how much I enjoy Fedora, and I think it
is an awesome distro. The question I have is, how exactly do you
configure the kernel to work on other machines in the rpm. Maybe I
didn't phrase that right, basically what I mean, is it seems that
during the install the kernel does some configuration on-the-fly (maybe
I'm wrong) and I was just curious how you             configure this
one kernel to work on various system setups. Also, what exactly do you
need to do to create the rpm of this kernel, do you configure it, then
do make rpm, or do you just do make rpm without any configuration to
leave a full kernel.
Thank you,
