From 7eb03a55d5cd2b6f4655183460c73cf3f2b4b5e1 Mon Sep 17 00:00:00 2001 From: David Cassany Date: Tue, 7 Nov 2023 21:48:49 +0100 Subject: [PATCH 01/10] Refactor grub as a bootloader interface This commit moves grub logic into its own bootloader interface. In addition it adds helper methods to find EFI binaries, kernel and initrd based on patterns. No longer a distro detection is required. It also sets an elemental criteria for those bootloader files. In fact first place to look at is /boot/efi/EFI/elemental, which gives a chance within the OS Dockerfile to prepare EFI binaries if default distro paths are not matching any of the default Elemental patterns. Kernel and initrd symlinks as /boot/vmlinuz and /boot/initrd are also created within the init command. This gives at build time more confidence that the kernel and initrd are set consistently with Elemental expectations. As part of the refactor BIOS firmware and MSDOS partition tables support is finally dropped.
