The launch of a new version of the Linux distribution, “Rocky Linux 9.0”, whose goal is to create a free version of RHEL that can replace the classic CentOS.

The new version of Rocky Linux 9 is the first version built with the new Peridot build system, created by the developers of the project, which supports iterative builds, allowing any user to reproduce the packages provided in Rocky Linux and ensure that they do not contain hidden modifications. Peridot can also be used as a tool to maintain and create individual distributions or to keep forks in sync.
