There is logic in the perform-action procedure in (guix scripts system) which adds GRUB to the PATH environment variable. That's where the determination occurs. So, currently, it looks like the 'grub-install' command comes from whatever version of grub happens to be defined in (gnu packages grub) at the time perform-action gets called. In practice, I believe this means that whatever grub version is currently available in guix (e.g., as seen via 'guix package --show=grub') will be used. Hope that helps! -- Chris
