Public bug reported:
[Availability]
* Groovy Universe
[Rationale]
* Needed to apply microcode updates, on bare-metal public-cloud
machines, that otherwise boot without a full initrd.
[Security]
* This package is tiny, just a single small shell script trigger hook
that create microcode-initrd from intel-microcode and amd-microcode
packages.
[Quality assurance]
* Installing this package automatically integrates with grub2 thus this
package needs no configuration to start using.
* There are no debconf questions
* Package is new, unique to Ubuntu
[Dependencies]
* All dependencies are in main
[Standards compliance]
* Complies with policy
[Maintenance]
* Foundations-bugs subscribed
[Background information]
* Currently we have a few public-clouds with bare-metal instance types
that boot without initrd. To apply microcode updates as required to
mitigate Spectre, Meldown, MDS attacks, a microcode-only initrd needs to
be loaded by grub, as late-loading of microcode is not safe. This
package was tested successfully on multiple instance types to ensure
correct operation.
