Thomas is right, that is not strictly speaking needed (but see below).

This is what I had in mind:
To make it work nicely, we should also add the dual logic to shutdown:
which will pivot back to the initramfs and unmount /usr cleanly. This
is where we need some busybox work, and I guess this patch should be
discussed a bit more, maybe it is not the best way to do it.

It is currently a mess. I agree with the people advocating putting
everything in /usr (and symlink /bin, /sbin and /lib for
compatibility). That obviously requires being able to mount /usr from
