In that case, you'll be prompted for those options when doing config/menuconfig/oldconfig, and you'll be told that it's a new option. > If you copy > some existing .config then it may not match the kernel that you are > compiling from source.

Yes. If you're using a .config file that you didn't generate yourself from an older kernel to compile a newer kernel, it's still fine to run oldconfig and get prompted for any new options. However, after doing that, you should do config/menuconfig, and verify the configuration. No, this isn't redundant. Doing oldconfig gives you the chance to configure any new options the way you want them configured, while doing config/menuconfig let's you verify the configuration, without having to worry that you might miss any new, and maybe important options. However, if your distribution's kernel version matches the kernel version you're compiling, I still think using the distro's .config will give you a good starting point. > > It is a pain to go through the config, but worthwhile to understand > what you need and don't for your hardware.

It's too bad there isn't a script for linux that can examine the hardware in a system, and generate a streamed down .config specific to that system. One of the neat things about netbsd is that there is a script that parses your dmesg output when running the netbsd-supplied kernel, and then it generates a streamed-down kernel config specific to your hardware.
