When you upgrade from 2.6.x to 2.6.y on Arch Linux, the package manager is going to remove all of the modules and other files associated with kernel 2.6.x. If you don't reboot, you're going to have issues if you need to load modules into the old kernel. Or at least, I'm reasonably certain that you will. There's a mechanism called kexec, which should allow you to switch kernels without a reboot. I've never used it, so I can't really say much about it. I'm not even sure that I'm brave enough to try it. -- Chris
