Also make a copy of the modules in /lib This way you can always have a kernel to fall back on. Personaly, I like the way that arch handles kernel updates, and dislike strongly the way e.g. debian do, where you after a while end up with 20 kernels installed, many of the same version, just with a different set of patches.
