Gentoo EC2 Tutorial / Bootstrapping

I want to accomplish a few things with this post.

First, I’d like to give more attention to the work recently done by edowd on Bootstrapping Gentoo in EC2.

Second, I’d like to introduce a few enhancements I’ve made on these (some being merged upstream already).

Third, I’d like to turn this into a bit of a tutorial into getting started with EC2 as well since these scripts make it brain-dead simple.
