Bug Description
Now that micorocode-initrd is in focal, linux-meta-aws should start depending on it in focal too.
--
[Impact]
* New package to provide micorocode-only initrd for application of microcode on boot, when otherwise no initrd is in use.
[Test Case]
* install microcode-initrd in AWS cloud x86 metal instance
* reboot, observe that microcode has been applied, and yet the boot was without initrd (observe journalctl -b -k to see that initrd was not used for boot)
[Regression Potential]
* This is a brand new package, that will be used by AWS images. Otherwise this package will not be automatically installed anywhere. Re spinning & promoting AWS images are tested and gated by the CPC team.
[Other Info]
* Original bug report for groovy:
Normally Ubuntu boots using initrd that has three archives: early amd64 microcode, early intel microcode, and compressed main initrd.
When booting without initrd, simply kernel is loaded without any initrd and thus without microcode.
However, grub supports booting with multiple initrds and one can specify a standalone early initrd which contains microcode only, and separate main initrd.
As an added bonus one can also specify just eary microcode initrd without a main one, to allow kernel to load microcode early, but otherwise boot without an initrd.
To achieve that I need to introduce a microcode-initrd package will will only provide early initrd which only has microcode.
The intention is to seed microcode-initrd to targets that boot on baremental without initrd.
