A check is done to make sure that the boot media matches the "install 
files".  The check is between the file .discinfo and the .buildstamp file 
in the initrd.

I assume you are installing from a "mirror" of the ftp.scientificlinux.org 
site.

The .buildstamp(in initrd) and .discinfo (in top level dir) have to 
"agree"

So you probably need to get the .discinfo file from your "install tree" 
and put it on your new iso image.

In SL4.x I did not rebuild the "install images" for the iso's.  Since I am 
using a different program for SL5 they get rebuilt.
