Yes, I already know why. I was able to check the program.log from the 
/tmp ramdisk in the ctrl-alt console and it is failing to assemble the 
raid arrays because of a bad argument ot mdadm. It is trying to assemble 
"/dev/md/0" instead of "/dev/md0" and the assembly fails, therefore the 
volume groups fail, therefore the filesystems cannot mount and then it 
reports that it cannot find the root of the existing installation. I put 
all this in the bug: https://bugzilla.redhat.com/show_bug.cgi?id=496258
