I would like to be able to set up a vehicle that I can choose wheather = to use v4 motor or v8 motor. That's so when I toss a car key to this = kid, he will only use the vehicle with V4 motor enabled. When I take = this same car key, I want to use a vehicle with a V8. Can both V4 and = V8 co-exist in a single vehicle? Kernel is similar to a motor in a PC. What's bad is that you also = re-compile every binary (make buildworld and make makekernel) to be = supported with amd64 optimizations to make it a amd64 system. You would = have to do the same if you want it to be an i386 system. You can't flip back and forth between a different architecture to = another architecture based on only the kernel swapping as you can do = with a car if you swap the motors back and forth (with huge amount of = physical work).
