Anybody who has been in ops for more than a few months takes it as a given and it's easy to rattle off a litany of reasons why it can't be any other way. If we stick with point releases, that might be true. Yet, if those same vendors are participants in a continuous development model, those delays could be reduced, perhaps even eliminated. If this is a thing members of the community want to develop, it's probably the kind of thing CentOS Stream should enable. -- Brendan Conoboy / Linux Project Lead / Red Hat, Inc. -------------- next part -------------- An HTML attachment was scrubbed...
