Hi Nick,

This grub upload only adds some extra pre-built binaries for BIOS and
IEEE1275. It does not change any bootloader code, and it does not even
rebuild the boot binaries for UEFI Secure Boot platforms (built by
grub2-unsigned).

The aim was to backport the removal of cd-boot-images from the ISO build
process to Noble. Originally the above debian-cd MP was meant to do that
for all arches, I believe, but it was scaled back to riscv64 as that
does not require any extra pre-built bootloader binaries:
https://code.launchpad.net/~adrianoco/debian-
cd/+git/ubuntu/+merge/484319

cd-boot-images are now considered pure technical debt and a not so good
idea, as they resulted in multiple boot incidents on Secure Boot due to
ISO images ending up with outdated bootloaders, and they have proven to
provide no tangible benefits.

With the above context, please let me know how to proceed? Or if the SRU
team wishes to keep the ISO build technical debt as opposed to the GRUB
changes? I am not so sure waiting till 24.04.4 is a good idea, given
that past precedent shows that these type of changes have a 99% chance
of not making it around such times due to business and de-
prioritisation.

Mate

P.S. Adriano is no longer @ Canonical, so I am taking over this now.
