In that case, you already need to install the kernel in order to test it, so you might as well install the headers along with it. Also, you're not normally touching multiple headers at a time, but rather add a feature in one file, so it's not hard to add it to both copies of that file. This may seem like an unnecessary step, but using the kernel headers without installing them first can cause any number of problems that we don't want anyone to have to deal with. Arnd
