Dnf Script To Cherry Pick Updates And Maintain RHEL Compatibility

Here’s an idea, though I don’t know if it would be practical.

I assume that at some point everything that goes into RHEL and its “official” updates travels through the Stream ecosystem beforehand.

So what about the idea of maintaining (somewhere) a list of official updates to RHEL as they are released, and then have some kind of a dnf enhancement or script that reads that list and updates a local CentOS installation using only the rpms on the list and ignoring everything else. Stuff that’s released to Stream would be downloaded and installed at the point where it has been released for RHEL and not before.

That would (I think) keep your CentOS installation in sync with RHEL.

    That (if it worked) would only work up until the stream reaches EOL at the end of ‘Full Support mode ‘- which for EL 8 is 31st May 2024 (not as we were expecting, sometime in 2029)

    Or even better, as Redhat appear to be taking full control of ‘CentOS’, why don’t they just make RHEL available to all for ‘free’, and you just pay for support if you need it – i.e. a bit like it is now, RHEL if you pay, CentOS if you don’t – I’m sure that would make everyone happy :-)

  • Because RHEL’s value proposition is not merely support, and the value of subscription goes way beyond that.

    Butttttt, that said: yes, this really is the direction things are going with expanded access to low-cost/no-cost RHEL.

  • Yeah, I have no insight into why the timing is what it is. But it is, so here we are. From what I’m seeing going on inside Red Hat I think there will be a lot of faith-restoring things coming up in the next year.

  • Matthew Miller:

    It that is really the case, then maybe some one from Redhat should pipe up now …

    If there is going to be a no-cost RHEL that can be used in the same way as CentOS is used now, then I think that would solve all the problems with this CentOS Stream announcement … and calm down things

    IMO – this does not work because no intermediate update will survive in the stream repos. If something moves on then the state that reflects the current RHEL release can’t be reached anymore. Or we have a mirror service that save all packages/stream releases …

  • There’s not going to be a no-cost RHEL that can be used in all of the cases where CentOS is used. But there will be options for a lot of cases. I want to be very careful that I’m not overpromising here because 1) I’m not in the business side of things so it isn’t even something I can directly influence let alone my call and 2) I do know that it really isn’t all worked out yet and won’t be for a little bit. But, I do know that Red Hat actually cares about these users and use cases.
