Is there a publicly available metric that tracks drift between security updates available in RHEL and Rocky?
E.g. what’s the time diff. between when a security update is available to RHEL and Rocky users.
I have found this answer, but wonder if this is being quantified and tracked somewhere.
P.S. https://repocompare.rockylinux.org/ is 403 at the time of writing.
There is not a page that tracks what you’re looking for.
The answer you are linking to is better clarified at our wiki. As this is a project lead and built by volunteers, 24-48 hours is the minimum. This is a general expectation, but cannot be assumed to be the rule. It can be faster or it can be slower, depending on volunteer time and severity of the updates that need to be built.
As an aside, the repocompare pages are dead, and even if it wasn’t, it was never a valid way to track drift. That wasn’t its purpose. Its purpose was for Release Engineering (my team) and the Testing team to verify our repositories are close to what is upstream. The closest you’re going to get when it comes to seeing what updates have been pushed by upstream and may or may not have been published by us is the incoming page. However, no one should be relying on this page for tracking anything as the page is not (and cannot be) 100% accurate. Use it as a starting point, but don’t rely on it as the absolute truth.
If your concern is having updates available as soon as possible, you may want to consider using RHEL with a developer subscription.
