That's perhaps easier, than to chroot (systemd-nspawn) and detailed
explained here:

The chroot or systemd-nspawn might still be useful, but indeed,
grub-install not necessarily requires it.

grub-mkconfig has got the -o option, so this should work without a
chroot too.

I suspect that chroot is only required, if there should be the need to
reinstall the grub2 packages.
