Unless I'm missing something  I'll end up with an initrd.img that will 
boot the
system I run mkinitrd on. It will not have the contents that the 
initrd.img has on
the CDs.

I've looked inside the /boot/initrd.img and
images/pxeboot/initrd.img and they have massive differences
in files in the img.
