I am aware, but going to a conference right now and flying back to
Europe next week, so I am unlikely going to be able to do much about
it for now.

I think they should all be offered, but I think we should make 0.9
the default for squeeze and move to 1.1 only afterwards, once
grub-pc knows how to deal with it.

mdadm does warn about /boot on array creation btw.
