Comment:
right, most bootloaders should support that, e.g. for efistub by append an initrd= option as `initrd=\ucode.img initrd=\initramfs-linux.img`

this tool https://github.com/anatol/ucode-image-gen seems capable of generating host specific images.
then one could edit our efibootmgr hook i guess?
