From 439de947262b0d8d4a02ca5afb1ef4f15853962c Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/9] Add BLS support to grub-mkconfig
GRUB now has BootLoaderSpec support, the user can choose to use this by
setting GRUB_ENABLE_BLSCFG to true in /etc/default/grub. On this setup,
the boot menu entries are not added to the grub.cfg, instead BLS config
files are parsed by blscfg command and the entries created dynamically.
A 10_linux_bls grub.d snippet to generate menu entries from BLS files
is also added that can be used on platforms where the bootloader doesn't
have BLS support and only can parse a normal grub configuration file.
Portions of the 10_linux_bls were taken from the ostree-grub-generator
script that's included in the OSTree project.
Fixes to support multi-devices and generate a BLS section even if no
kernels are found in the boot directory were proposed by Yclept Nemo
and Tom Gundersen respectively.

Otherwise, we end up looking for kernel/initrd in /boot/boot which
doesn't work at all. Non-emu builds need to be looking in
($root)/boot/, which is what this is for.

Subject: [PATCH 5/9] blscfg: check for mounted /boot in emu
Irritatingly, BLS defines paths relatives to the mountpoint of the
filesystem which contains its snippets, not / or any other fixed
location. So grub2-emu needs to know whether /boot is a separate
filesysem from / and conditionally prepend a path.

Subject: [PATCH 6/9] Follow the device where blscfg is discovered
Previously, the code assumed that GRUB_BOOT_DEVICE "($root)" was always
the correct device for the discovered bls menu. However, this assumption
could lead to inaccuracies when attempting to load bls for devices other
than $root.
This patch introduces a more robust approach by utilizing the `struct
find_entry_info *info->devid` parameter, representing the device used to
discover the bls directory. This change ensures consistency in
subsequent translations to native GRUB commands, eliminating potential
discrepancies in device identification during the blscfg process.

Subject: [PATCH 7/9] grub-switch-to-blscfg: adapt to openSUSE
A few tweaks to make it 'just works' for openSUSE:
- remove RHEL specific $grub_get_kernel_settings and all reference to it.
- make $grubdir and $startlink to the path in openSUSE
- change the bls template to openSUSE
- make $cmdline account for btrfs subvolumes, among others
- remove RHEL specific $GRUB_LINUX_MAKE_DEBUG and all related code
- remove ostree specific hack
- ignore increment.mod

From 2b0e6effc31ec166bbbe35a3cd2b4c73051f38bb Mon Sep 17 00:00:00 2001
From: Michael Chang <mchang@suse.com>
Date: Fri, 16 Jun 2023 15:54:50 +0800
Subject: [PATCH 8/9] blscfg: reading bls fragments if boot present
The Boot Loader Specification (BLS) designates the EFI System Partition
(ESP) as a primary location for $BOOT, where boot menu entries can be
stored. The specification encourages boot loaders to retrieve menu
entries from the ESP, even when XBOOTLDR is present.
This commit aligns with the BLS specification by introducing the
capability to search for the ESP in addition to the default root
partition or any specified location via blscfg's command line. The $boot
environment variable is utilized as a reference to the ESP device for
the blscfg command. Initialization of $boot in grub.cfg is demonstrated
as follows:
insmod part_gpt
insmod fat
search --no-floppy --fs-uuid --set=boot F414-5A9F
If $boot is unset, no additional search for the BLS location will be
performed.

Subject: [PATCH 9/9] 10_linux: Some refinement for BLS
Remove BLS_POPULATE_MENU as it is not being used currently and removing
kernelopts assignment in the grub boot config itself to fully delegate
the responsibility of generating kernel options to a functioning BLS
generator.
