AH! Yeah, that should work then.

I still get leery of people talking about manually partitioning their drives because of a horror story someone once told of losing the partition during an upgrade once because they'd done it manually and it wasn't exactly the same as the way the builder does it. It worked fine right up until the point where they applied the next software upgrade and then poof.

But I definitely trust Roger's instructions, so yeah, that should work.
