RAID install document

Hello,

I'm trying to build a simple (all) raid 1
workstation. Just boot/root/swap like
what is found in the handbook.
  Is this the best document to follow:

http://en.gentoo-wiki.com/wiki/RAID/Software

Since grub2 is now defacto and drive sizes
are routinely over 2T, I guess that Disk-labels
(UUIDs), fstab, gpt and grub2 should all be used
to 'future proof' installations?

There is only a snippet in the handbook
and it couches these and other related issues
around multilib.

Any better, more complete documents are keenly
appreciated.


James
