1] If you want to put Grub2 into partition, you can use filesystem, which reserves enough space at the beginning like BtrFs.
2] You can also use calculated block size which is less safe but still works in most of cases

In those cases you can use either `multiboot' to chainload GuixSD's bootloader or just load GuixSD's configuration with `source'.

3] You can use GuixSD's configured Grub2 as your default bootloader in MBR of the disk which is the easiest way to deal with that.

Relying on unmaintained Grub is probably not the right way for anything.

HTH and happy New Year to you too!
