If you take the wiki slowly, you'll hopefully grasp what's going on.

Especially the bit about setting up a new system or converting an
existing system. Okay, they're not at all about what you're doing, but
if you work your way through and get what's happening there straight in
your head, you'll then be able to apply it to your setup.

Note that they're written from my perspective as a gentoo user, so I
have to do everything from scratch - boot into a live/rescue CD, and
then configure/setup the system from there.

Just checked those two pages (should have done that before I hit send
:-) and they're not quite as appropriate as I thought. Still worth
reading, though.

But that's given me an idea for more detail in the wiki, so this should
lead to further improvement :-)
