partition from /. If so, copy the kernels and initrds to /boot and
use paths relative to /boot in the GRUB configuration file. This
makes the boot.loader.grub.bootDevice option obsolete. (Is there a
way to mark obsolete options?) It also makes it unnecessary to set
boot.loader.grub.copyKernels, although that option is still
available since it can speed up GRUB if the Nix store is very
large.
