       I really really hate the term "bug-to-bug compatibility". I hate how #RHEL clones story normalized it and people now talk about it like this is the main and only thing in the world.While it doesn't make any technical sense.Why?Because ask yourself - is RHEL bug-to-bug compatible with RHEL?

       @bookwar ABI or runtime compatible? just userland is not even correct as it is about kernel+userlandis RHEL b2b-compatible with CentOS?

       @gbraad ABI compatibility is also a myth :)The guaranteed ABI compatibility of RHEL is described in this document:https://access.redhat.com/articles/rhel9-abi-compatibility which people rarely read. There is also _assumed_  ABI compatibility of RHEL. As it is a LTS distro in a common sense.The important part is that every CentOS Stream 9 change is a RHEL 9 change which goes into next minor release.CentOS Stream 9 is ABI compatible with RHEL 9 the same way how RHEL 9.2 is ABI/binary compatible with RHEL 9.3.

       @gbraad If I am a vendor, and I support my software on RHEL 9, it means I must support it on all RHEL minor releases. It naturally means that I must support (in tech sense, not business sense) them on CentOS Stream 9 as a preview of the next minor release.If my software fails today on the CentOS Stream 9 while it works on RHEL 9.2, as a vendor I am in a big trouble and need to fix it ASAP, because my customers will update to 9.3 as soon as it is out.1/

       @bookwar @gbraad Working with Stream for pre-testing should be quite common for ISVs or anyone planning to support RHEL. It gives you all you need plus what’s coming. And you can solve issues long before the new RHEL hits your users/customers.

       @gbraad The whole point of CentOS Stream is to allow vendors to do this integration testing together with RHEL engineers developing RHEL, so that they don't get any surprises on the next minor release.We have CS9 infra to help them automate it.Vendors are slow moving, so it is not happening immediately. But if a vendor ignores CentOS Stream issues, that's kind of tells you a lot about the quality of that vendor. 2/2
