Also, please keep in mind Ludo's suggestion of using the first class profiles
of G-Expressions. I'm not sure it's applicable in this case (!)--but still, it
would be nice, for a future version of raspberry efi netboot or of similar
things, to be able to do this, right from config.scm:
(operating-system
(bootloader
(bootloader-configuration
(bootloader ; field in bootloader-configuration
(bootloader ; bootloader record constructor
(inherit grub-efi-netboot-bootloader) ; so we have the installer
(package ; override bootloader's package
(profile ; create a profile
(content
(list (file-append firmware "/boot/")
(file-append u-boot-my-scb "/libexec/u-boot.bin")
(plain-file "config.txt"
"kernel=u-boot.bin")
(bootloader-package grub-efi-netboot-bootloader))))) ; and
put the package we've overridden back into the profile
(target "/boot"))))
This way, maybe the procedures efi-bootloader-chain and
efi-bootloader-profile would be superfluous.
Note: I haven't used this myself yet.
