Here's a WIP patch that I'd like some advice about. It does insert the
relevant text into grub.cfg, although I recommend testing it in a
virtual machine for now.

Questions:

1) In general, is this approach okay?

2) I think that (grub-setup-io) should be used in
(grub-configuration-file) instead of (eye-candy). But, when I try
calling it there, in the builder, it has no effect on grub.cfg. Any
suggestions for debugging this?
