That's a heckuva trick, booting from a file system your kernel doesn't
support. How does the kernel know how to read the file system to mount
root, then? Sure, you can boot the kernel, but it will panic because
it can't mount the RFS. So, you either have to have XFS support compiled 
into the kernel (what I do here) or it has to live in an initrd.
