This was what I suggested in my mail, but it does add network overhead
and means that if you had 100 hosts relying on your pxe server and it
failed after a mass kernel patch (+ reboot)! I would rather rely on
less points of failure by booting BIOS -> hdd. The cost of this is a
one-off powerdown, and if you are keeping up with kernel revisions
this shouldn't be too long to wait?
