To handle this, we can place the bootloader file in the UEFI specification location, overwriting any other OS that may have placed a file there. This location is namely /boot/efi/EFI/BOOT/BOOTX64.efi. Grub has explicit support for this location/situation with the `--removable` flag. * gnu/bootloader/grub.scm (install-grub-efi-removable) (grub-efi-removable-bootloader): New variables. * doc/guix.texi (Bootloader Configuration): Document it.
