Since the background with the GNU head seems to work, here is modified
version. I made the head a bit more visible and moved the Guix logo to a
corner.

I just sent a request to join the project in Savannah.

You have to set the following options in GRUB configuration:

GRUB_GFXMODE
GRUB_BACKGROUND

I would provide one SVG version of the background for the following
aspect ratios: 4:3, 16:10, 16:9. Then, you build PNG versions in
specific sizes (for example, 1024x768, 1440x900, 1920x1080).

Ideally, GRUB should be able to decide what GFXMODE and BACKGROUND to
use for every screen. However, the last time I provided GRUB stuff for
gNewSense (for GRUB legacy), GRUB would determine the display size and
use the same background image (a 640x480 PNG) for all aspect ratios.
This resulted in stretched background images, so usually we would make
the image as simple as possible: no text or shapes, just a background
with gradients.

But, since Guix is using GRUB 2, which is supposed to be more flexible,
we should at least try to see if it can use an appropriate image for a
given display.
