I've noticed for some time now that some distros are upgrading the current running kernel, rather than installing a new kernel version, which if there are problems with the new kernel, you could boot the earlier kernel, which you know was working ok.
I'm currently updating my Don't Panic install, and there is a kernel update to 2.6.25.4-1 , and 21% done so far. Is there some way that this latest kernel version can be installed as a new kernel, and leave the existing one alone?
I don't like this way of updating the kernel, as you have no way of booting to the earlier one if the latest version is problematic.
26% done now.

There is a realy simple solution to this one: Make a copy of the the kernel, initcpio and System.map that you want to keep, and add an entry in grub that points at it. 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.
