It all depends on how adventurous you are today :) Using a defconfig
will work, and you can generate one without much trouble. Using
fragments will allow you to keep your changes separate from the
baseline configuration, but you'll need to tweak the recipe .. which
always carries a risk of some unexpected side effects.

I'm around to help regardless of which way you chose.
