There are multiple places within Kayobe and Kolla where we would need to set this sysctl to fix our CI, including backports to all supported branches. I was wondering if infra could instead customise their stream image or apply the sysctl in one of the common roles from zuul/zuul-jobs that are run at the beginning of each job? Many thanks.

How close are the CentOS Stream maintainers from uploading a regression fix for the package? If it's going to be a while, then the safest solution is probably to add a platform-specific DIB element and rebuild our centos-8-stream images with that. Making modifications to our "base" job (or any of the roles it uses) is far more time consuming and likely to take a lot longer, because of the precautions we take in order to avoid accidentally breaking every job in the system (changes to the "base" job are not directly testable).
