Yep, that worked a treat, thanks!  :)

I gave that a quick try, and disklabel wouldn't let me write a partition
that wasn't on a cylinder boundary.  I gave up rather quickly and used
the first method instead, because I wanted to get the box up and running.
I have another box, and will probably try it again soon.
