The restore process with the patch set is as follow:

Why is a third kernel needed? Why can't kernel B be used for this as well? In fact, if kernel A has been compiled to be relocatable and crash dump enabled, why wouldn't it suffice for all 3 instances?

you could use one kernel for all three, or you could use three different kernels, and three different sets of userspace if it's appropriate.
