[CentOS-devel] Kernel used on installation media.

Hi all, I hope this is not too off topic.  I've searched the -devel archives,
but haven't found clear-cut information on this, so thought I'd ask.

I am trying to determine the kernel configuration used to build the kernel
used on the installation media (CD #1 or the vmlinuz/initrd.img files in their
respective images/boot.iso or images/diskboot.img files).

My guess is the kernel configurations are not identical to the ones ultimately
used to build the kernels used on the system once it is up and running....

I ask because I am interested in rebuilding the kernel used on CD #1 to boot
into the installer.

Thanks for any pointers.
