OS new release support cadence

General Discussion

As we’ve mentioned elsewhere, Open OnDemand 4.1 (to be release very shortly) will add support for Enterprise Linux version 10 in terms of providing compiled binaries. Likewise, we are going to stop providing compiled binaries for arm64/aarch64 since they are pretty difficult for us to create compared to the community usage.

This begs the question as to what other OS’s the community might be interested in us supporting in similar ways (and when we might potentially drop support for older ones).

We’ve done some Splunk reports and have compiled the below stats regarding unique sites downloading the various types of packages we make available over the past 12 months (for calendar year 2025).

Architectures:

  • arm64|aarch64: 102

  • amd64|x86_64: 6,711

  • ppc64: 8

OSes:

  • RedHat/Rocky Linux/AlmaLinux 8 / el8: 2,204

  • RedHat/Rocky Linux/AlmaLinux 9 / el9: 2,728

  • amzn2023: 295

  • Debian 12 / bookworm: 179

  • Ubuntu 20.04 / focal: 318

  • Ubuntu 22.04 / jammy: 1,172

  • Ubuntu 24.04 / noble: 605

Debian 13 / trixie was released in August. Is the OOD community adopting it?

Likewise Ubuntu 26.04 / resolute will be released in April. When might we consider starting to support it?

Are there other major ones we should consider such as Azure Linux?

I would like to see work done for the Ubuntu 26.04, and the Rocky/RHEL/Alma 10 go forward.

SLES/OpenSuse 15.4 would be nice to have. That is what our clusters run. I’m using Rocky 9 on the OOD servers now and that seems to be working fine, but it would reduce some maintenance if they could run the same OS.
