Hrm. <puzzled look> How would I then start my md0 raid-1 array that is
mounted as the root partition / if I'm not doing this when the kernel is
starting up? Because without it I've got no userspace to actually execute.
Some of the other arrays with things like /var and /home could obviously be
easily assembled soon after the kernel hands over control to userspace before
the filesystem points are mounted, but for the root I am not quite sure how it
could work...
