AlmaLinux OS - Forever-Free Enterprise-Grade Operating System
almalinux.org
An Open Source, community owned and governed, forever-free enterprise Linux distribution.

In reaction to the recent announcements by RedHat, AlmaLinux is shifting focuses slightly:

We will continue to aim to produce an enterprise-grade, long-term distribution of Linux that is aligned and ABI compatible with RHEL in response to our community’s needs, to the extent it is possible to do, and such that software that runs on RHEL will run the same on AlmaLinux.

That is, instead of “1:1” bug compatibility, they will aim to be ABI compatible.
