This sounds like a great idea, but I'm trying to imagine how this would 
work. It can't be enough just to copy the root partition over to another 
partition, you also need to make adjustments to the boot loader, and you 
need to differentiate between the cases where you are actually upgrading 
the kernel and when you are upgrading other packages. I tried to find a 
tutorial that might explain how to do this using grub, but didn't 
couldn't find one. Does anyone know of instructions about this?
