Public bug reported: upgrade amd64-microcode with new microcode & better initramfs hook
[Impact] * New microcode is available * It is hard to generate initrd, with all microcodes included because the initramfs hook ignores preset defaults. Adjust hook to take preset defaults into account. [Test Case] * There is no testcase for new microcode, as it is unknown what has changed. * Install new package, and check that initrd with default settings (i.e. modules=most) has amd64 microcode included. And that with modules=dep|list it only does so, if one is on AMD cpu. * Install initramfs-tools-ubuntu-core from snap image PPA, the resulting initrd should contian both amd64 and intel microcode, despite using modules=list, due to the conf.d default settings it overrides. [Regression Potential] * New microcode is published without a changelog, thus it is unknown what it fixes or regresses, yet it is recommeded to upgrade it. The 17h family microcode has been updated, almost doubling in size. * The hook default behaviour is not changed, only integration with custom conf.d's is improved. * This both shows the SRU team that the risks have been considered, and provides guidance to testers in regression-testing the SRU.
