From 41b34441c22143cbabace3d794ead05801afb7a0 Mon Sep 17 00:00:00 2001 From: "Ng, Wei Tee" Date: Sun, 23 Jul 2017 16:51:56 -0700 Subject: initramfs-framework: include install-efi module in recipe for installation Utilized the existing init-install-efi.sh script and renamed it to install-efi.sh to manage the installation process of images in initramfs-framework model. This script will be executed when "install" option is being chosen in the grub menu and install the image on the target platform. A new install-efi module is being added in the recipe to handle the installation process using initramfs-framework.
