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.
