custom kernel config

[Efraim Flashner <efraim@flashner.co.il>]

[-- Attachment #1.1: Type: text/plain, Size: 596 bytes --]

I'm playing around with the idea of creating a custom kernel for my
laptop and I started by following Gentoo's kernel config instructions.
I'm including what I have currently. I want to create a kernel which is
good for my laptop and takes less time to build than the standard
kernel. By leaving the #:configuration-file blank I'm only filling in
the fields I supply, right?
