    Kris, I don't think putting anything more than a pointer to
    books/handbook/kernelconfig-trouble.html in the FAQ would be
    sensible, and I'm not sure that would be more than just needless
    bloat either. It's hard to find "your" question in the FAQ by visual
    scanning already.

    FAQs are piles of documentation snippets nobody bothered to
    streamline into proper documentation, which in the case of FreeBSD
    is the books and articles. Please find a place for this in
    books/handbook/kernelconfig-trouble.html.
