I can't believe I'm suggesting this (we've come full circle now) but we cou=
ld add a new bootloader in gnu/bootloader/grub.scm,=20

(define* grub-hybrid-bootloader ; or grub-mkrescue-bootloader, maybe less m=
isleading.
  (bootloader
   (inherit grub-efi-bootloader)
   (configuration-file-generator grub-configuration-file-without-search-emi=
ssion) ; this here could parametrize grub-configuration-file somehow or may=
be we could refactor grub-configuration-file instead.
   ; Note: name is still 'grub-efi, so the public boot parameters API doesn=
't change.
   (package grub-hybrid))) ; probably; or grub-efi if you just want a quick=
 test with EFI only.

... and use it in iso9660-image or gnu/system/install.scm .
