;; This is an operating-system configuration template of a
;; 64-bit minimal system for a Raspberry Pi with an NFS root file-system.

;; It neither installs firmware nor device-tree files for the Raspberry Pi.
;; It just assumes them to be existing in boot/efi in the same way that some
;; UEFI firmware with ACPI data is usually assumed to be existing on PCs.

;; It expects the boot/efi directory to be served via TFTP and the root
;; file-system to be served via NFS. See the grub-efi-netboot-bootloader
;; description in the manual for more details.
