Hi Abdalla,

We, ALS-U, plan to use Rocky as the primary OS platform. We are using it for the development environment, not the production yet.

If you can look at the Rocky development history carefully, you can find the original developers of CentOS. Rocky is the name of one leading developer for the CentOS project. And since historically, the current founder was the ALS UNIX group member, our UNIX group has a strong preference for Rocky also. It doesn't have a substantial milestone, but their support time is ten years at this level. However, you also have to decide what to use because this is open-source software.

Technically, our entire software platform is independent of any major Linux distribution. From minimal costs, we can migrate every environment to different platforms quite quickly because our environment isn't dependent upon any other specific tools (except makefile and bash). And we test every software within all significant platforms within the GitLab CI environment with several in-house Docker environments. My recommendation (Other facilities may disagree) is to keep your environment independent upon a specific Linux distribution. That is what I am trying to do.

My personal preference is still Debian, but I am now using macOS more than Debian. However, still, our environment supports them all (macOS as well) without any issues. So migration doesn't cost much from A to B from my view.

Thanks,
Han

Hello

 

Well this is not directly about EPICS but it does affect control and IT infrastructure in general. As you know, CentOS 8 will reach end-of-life by the end of 2021 and CentOS 7 in 2024 following the decision that CentOS will become a rolling-release instead of a stable, RHEL downstream release. We are now investigating the possible alternatives on what to have instead of CentOS, whether purchasing a RedHat license (very much expensive), going with a RHEL-compatible CentOS alternative (Rocky Linux, Oracle Linux, Alma Linux) or continuing with CentOS stream and work on periodic update policy.

 

I know that Rocky Linux released its first stable release on June, but the project is still new and it is still unclear how much further it will become a CentOS replacement. I would like to have feedback from the community what they are using now and if they are using RedHat or CentOS, what are their plans for the future.

 

Best Regards,

Abdalla.
