This should really have the same behaviour as ``make installkernel''.
After moving the kernel to kernel.old it should update kern.bootfile and
it should not backup kernel => kernel.old if kern.bootfile already points
It's bad if two kernel upgrades without an intervening reboot blow away
your running kernel :(
