A number of you have already shifted over to CentOS 8 Stream in CI (thank you!), but there is still quite a bit remaining based on codesearch and some manual digging. The OpenDev team has begun the process of removing some of the supporting infrastructure and testing as well [1].

I think that we can give it until the end of January before we force merge updates to remove the nodeset and label from our configs. At that point any Zuul configuration still using CentOS 8 will enter an error state and correcting it will be necessary to make updates to those Zuul configs.

Devstack has replaced the CentOS 8 to CentOS 8  Stream until stable/wallaby[1]. We can remove the CentOS 8 or
replace it with CentOS 8 Stream for other older stable too.
