高エネルギー物理学の研究業界は　CERN/FNAL の決定待ち
本当は2021年Q1の間（３月末まで）にアナウンスが出るはずだけど、アナウンスが遅れている

How is CERN going to adapt to this?¶

CERN acknowledges the recent decision to shift focus from CentOS Linux to CentOS Stream,
and the sudden change of the end of life of the CentOS 8 release. This may entail significant
consequences for the worldwide particle physics community. We are currently investigating
together with Fermilab the best path forward. We will keep you informed about any
developments in this area during Q1 2021.

- there is no explanation how CentOS Stream is a technically acceptable replacement
for CentOS Linux. There is many questions here, none answered.

全くその通りで、これまでRHELのクローン（安定版）で普通に業務にも使えていたCentOSが
開発用不安定版のバクだしのための、CentOS Streamに置き換えらられるはずがない！　下にも同様のレポ。

When the Centos 8 news came out, I tried out Centos Stream against our configuration. Kickstart and Puppet config
needed very little change and I was able to bring up a VM in our lab config quite easily.
I have two observations:

1) Updates are sparse, none for ages then a large batch of version updates.
2) Stuff can be broken and remain so for a long while. We use Podman rootless. That was broken in the version of Stream
I initially installed and remained broken for a few weeks until the next chunk of updates. I looked up the issue in the RHEL
tracker and it had been fixed quickly in Fedora etc. but this did not make it to Stream on the same timescale.

My view is that Stream is exactly what RHEL say it is, a development distribution to which 3rd parties can contribute to
RHEL development and from which 3rd parties can base their own distributions. It's not for end users, or small
organisations that need timely security updates and other fixes and can't produce same themselves.

Update on CentOS Linux strategy

25.10.2021

CERN and Fermilab have been closely evaluating the Linux distribution landscape.
We observe that national cyber infrastructure organizations are increasingly
supporting more science domains, so in addition to LHC- or HEP-specific
considerations, it will be useful to have a choice that is widely recognized
and meets the needs of broader science research.

Red Hat has made a proposal to CERN regarding an academic licensing scheme.
Ultimately this would require significant overhead at external sites, and
therefore we have worries on this proposal’s attractiveness for other sites.

Going forward, we propose to target CentOS Stream as the standard distribution
for experiments. We feel that deploying CentOS Stream 8 is low risk, and we now
have months of experience running IT services and experiment offline workloads
on CentOS Stream 8 without any significant issues.
We feel that should issues arise with the adoption of CentOS Stream 8, it would
be straightforward to reevaluate other options before CentOS Stream 8 support
ends. CentOS Stream 8 is a supported distribution until May 2024. Trivial
migration paths are provided by the various ELC (Enterprise LinuxClone)
communities.

Continued support for existing workloads on Scientific Linux 7 and CERN
CentOS 7 will be maintained as previously planned.

Fermilab/CERN recommendation for Linux distribution
08.12.2022

CERN and Fermilab jointly plan to provide AlmaLinux as the standard
distribution for experiments at our facilities, reflecting recent
experience and discussions with experiments and other stakeholders.
AlmaLinux has recently been gaining traction among the community due
to its long life cycle for each major version, extended architecture
support, rapid release cycle, upstream community contributions, and
support for security advisory metadata. In testing, it has demonstrated
to be perfectly compatible with the other rebuilds and Red Hat Enterprise
Linux.

CERN and, to a lesser extent, Fermilab, will also use Red Hat Enterprise
Linux (RHEL) for some services and applications within the respective
laboratories. Scientific Linux 7, at Fermilab, and CERN CentOS 7, at CERN,
will continue to be supported for their remaining life, until June 2024.

Hello,

The end of Scientific Linux is near. Following the upstream release cycle:[1]
On June 30, 2024 Scientific Linux 7 will reach End of Life.
No security updates for SL7 will be published after June 30, 2024.
After June 30:
The installation trees will be moved into the 'obsolete' directory.
Kickstart and yum operations against the old repository locations will no longer work.
the official docker images for SL7 (docker pull sl:7) will be retired
A copy of the final docker image will be placed in the 'obsolete' directory under 7x/x86_64/os/images/docker.
The files themselves will remain available under the 'obsolete' directory.[2]
Users of Scientific Linux 7 should migrate to an actively maintained operating system. At Fermilab, AlmaLinux 9 is the recommended choice.[3]
AlmaLinux 8 is available for folks as well.[3]
