Handbook btrfs support

I was looking at the handbook. File system support seems limited in the 
documentation of the handbook, some quite antiquated (reiserfs?).

Looking at the handbook it would seem to be quite extensible to support
one of the newer, extremely attractive, files systems (ZFS or btrfs).
My guess is that, license_wise, it would be easier to document the
use of btrfs in the handbook?

So, these are the sections that would need only limited prose to support
btrfs in the handbook:

2.b
4.b/4.d  4.e
6.a 6.b
7.b
8.a
9.e
10.e ?

The idea would be to use a single 2T drive, with the standard
(handbook) 3 partition scheme, with just the simplest gentoo system
set up with BTRFS.

Your comments and suggestions are most welcome. If this idea is deemed
meritorious, I'll take a crack at it and post what I discover after
performing a few of this proposed btrfs handbook installs?


your thoughts?
