That's pretty obvious with any system, really, no need to repeat that. I think this topic was raised multiple times (by you and others already) to realize that. In an ideal collaborative world, perhaps, those 3rd-party drivers could be build and tested automatically on top of the CentOS Stream, though we are yet to reach that point of collaboration. Following your approach to a detailed information about the Stream, we've been told there are various RHEL subscription programs coming next year that would address use of RHEL for many existing CentOS users. Perhaps, those programs would address the needs of consumers of 3rd-party drivers too, before we'd reach the collaboration ideal I outlined above. Let's see how that goes. -- / Alexander Bokovoy Sr. Principal Software Engineer Security / Identity Management Engineering Red Hat Limited, Finland
