bootloader: grub: Add support for loading an additional initrd.
In order to be able to provide decryption keys for the LUKS device, they need to be available in the initial ram disk. However they cannot be stored inside the usual initrd, since it is stored in the store and being a world-readable (as files in the store are) is not a desired property for a initrd containing decryption keys. This commit adds an option to load additional initrd during the boot, one that is not stored inside the store and therefore can contain secrets. Since only grub supports encrypted /boot, only grub is modified to use the extra-initrd. There is no use case for the other bootloaders. * doc/guix.texi (Bootloader Configuration): Describe the new extra-initrd field. * gnu/bootloader.scm (<bootloader-configuration>): Add extra-initrd field. * gnu/bootloader/grub.scm (make-grub-configuration): Use the extra-initrd field.
