It's not incorrect, per se, but this was a simple way to get the
install-os functionality to work without significant refactoring.

I just recenty booted and refreshed the guixsd installation on the
novena I had, and was reminded that installation of the bootloader
required manual intervention from the user, and could potentially result
in an unbootable system of the SPL/u-boot.img were sufficiently out os
sync.

The more complicated way would be to make novena-installation-os and/or
embedded-installation-os smart enough to drop "u-boot.img" in the
correct place, on the first FAT or EXT* partition of the microSD. That
is certainly currently over my head to attempt that at the moment.

I think we had touched on this in the bugs where I introduced
u-boot-novena in #31404.
