GRUB 2.12 brings many improvements including, but not limited to,
detached LUKS keyfile support, and numerous fixes for file system
behaviour, compared to GRUB 2.06.
GRUB 2.12 also improves memory allocation in GRUB, making it less
likely to run out of memory when a lot of memory is used, like when
having a very large memdisk.

The "Load Operating System (incl. fully encrypted disks) [o]" GRUB
entry tries to load grub configuration files from the hard disk or SSD
partitions. It tries various files in /boot, /grub, /grub2,
/boot/grub, /boot/grub2.
For consistency we at least need to make it search for the
gnuboot_grub.cfg in these directories as well. Since this is GNU Boot,
the gnuboot_grub.cfg takes precedence over files made for other boot
software distributions.
For libreboot_grub.cfg, it was not replaced because it is still
mentioned in the documentation.

with this change, it's unlikely we'll hit errors again. previously,
some projects used were calling "python" which in context was
python3, but on some setups, the user only has python2 and python3
but no symlink for "python" (which if exists, we assumed linked to
python3)
now it's unambiguous. docs/build/ can probably be updated now, as
a result of this change, to remove the advice about that
hardcode everything. in practise, the new logic will work just the same in
almost all cases, for most people, but it works around performance issues in
grub. cleanup of grub.cfg will be done in the next commit
On many boards, grub takes a very long time to
search for a grub.cfg file on the disk.
The problem is the search_grub function which
takes a long time to complete.
I (vitali64) studied the grub.cfg from 2016 and
the grub.cfg from 2021 and optimized the
grub.cfg. It should be faster now.
tianocore is a liability for the libreboot project. it's a bloated mess, and
unreliable, broken on many boards, and basically impossible to audit.
i don't trust tianocore, so i'm removing it.
There is already a separate menuentry for USB, and most people don't boot their
installed system from USB anyway. This will result in faster boot speeds.
mitigate missing characters in unifont for border/arrow characters. this saves
space because now it is no longer necessary to add a custom font
the background added has the libreboot logo on it, and it's 10kb in size unlike
the old gnulove background that was hundreds of KB
this is a compromise. i was going to do 30 for desktops, 1 for laptops.
however, some laptop users complain about the 1 second timeout being too fast.
10 seconds should just about please everyone.
this is forked from the "libre" branch in osboot, which is itself a libre,
deblobbed fork of osboot, a blobbed up fork of libreboot
libreboot needed to be purged clean. this is the new libreboot development
repository. the old one has been abandoned
