First, you have installed a new world which has to run with an old kernel. This WILL fail in some cases and is almost impossible to gracefully back out of. (Last major case was an update of GNU utilities at about V4.1.) Second, your have installed world and rebuilt the kernel which puts you in a really bad position if the new kernel does not work. I think I could recover with a lot of pain, but others have suggested that the best recovery from this is to re-install the system from scratch. The order recommended in the handbook was discussed at GREAT length to provide the greatest immunity to failures in the process and the easiest recovery if things go wrong, as they will some times.
