If you look in the logs you'll see where I had to copy and modify the 
bootloader line for the Upgrade to Rawhide entry. I had to use NFS in 
order for anaconda to find the kickstart file. Otherwise anaconda hits 
the other bug that I filed where it cannot find the kickstart file even 
when you give it the proper device and path. This may also be due to it 
being located on a raid array. Anyway, using NFS got by that problem and 
then I ran into the next problem where it was trying to assemble the 
raid arrays using the wrong names.
