------- Comment From [email protected] 2019-09-24 09:11 EDT------- Yes this only updates the description. The name gen15a can not be changed without hurting migration compatibility. We are looking into adding an alias for cpu names, but this would be a future change. With that medium priority is fine.

The cpu type itself that is used in e.g. scripts / commands will not change. Therefore the regression risk of the qemu change is next to none. The only I can think of is people grepping for the old ID in text output, but that seems theoretical and not important. [Other Info] * For an SRU perspective this is "nice to have" we will only do this "along" other higher impact SRUs. __________ This feature request will provide the final naming of the next machine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1842774/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
