It shouldn't, but it should eventually be smart enough to figure out
which of the two mirrors has the 'most recent' data.

And it should try to load a kernel via multiple drives until it finds a
kernel+initrd combination with a good checksum. 

This would also help raid1 + multipath boot scenarios, as long as the
boot loader itself got started "somehow".
