Currently, I don't think Guix supports a way to specify a chainloader
command in your GuixSD operating system declaration. That may change in
the future, but today I think that's how it is.
This is because the <menu-entry> record type (see: (guix) Bootloader
Configuration) does not expose any fields for a chainloader command, nor
does it provide a way to supply an opaque configuration file. I think
the motivation for apparent limitation is that <menu-entry> is intended
to represent an abstract menu entry, suitable for use by various
bootloaders, and (maybe?) not all bootloaders may support chainloading.
GuixSD supports GRUB and U-Boot. Does U-Boot support chainloading, like
GRUB does? I'm not sure.
