	We did something similar when we went from 4.2 to 4.3; we left our
4.2 root where it was and stole the /tmp partition to put the 4.3 root on.
We had copies of both kernels on both roots, with 4.3 having a hacked-up
partition table.  If 4.3 bombed (which it did a lot until we got our act
together) we could back out easily.

	We ran that way for a few weeks.  It worked fine, but yes, it was
confusing as hell.
