Heh, I dare say most of us are lost on this one. It is a blinking new 
module for md that is not available on Centos 4. This should help us 
deal with any future questions from people asking, "How do I create a 
raid10 array for root during installation?" or similar. Answer: You 
cannot not. But you can do raid 1+0/0+1.
