Red Hat Enterprise Linux (RHEL) braccato da AlmaLinux 9.4

Red Hat Enterprise Linux (RHEL) braccato da AlmaLinux 9.4

When Red Hat announced the divestment of CentOS in favor of CentOS Stream, an irreparable rift was created between the company and the community. The grumblings of many developers belonging to the world of free software have led to the birth of some alternative distributions, including the popular AlmaLinux, which we have presented in detail in a dedicated article. Red Hat Enterprise Linux (RHEL) 9.4 was released in early May 2024 but it took just a week for it to arrive AlmaLinux 9.4.

And that’s really no small thing. While in fact CentOS was a binary clone of RHEL, AlmaLinux is designed to be compatible at the binary level with RHEL, but it is by no means a 1:1 clone.

AlmaLinux 9.4, just one week after RHEL 9.4, is a victory for free software

AlmaLinux cannot be a 1:1 clone of RHEL due to security issues license. In fact, Red Hat announced some time ago that it will not make the tools available for creating derivative projects. As, AlmaLinux OS Foundation he staked everything on maintaining the flood compatibility With the’Application Binary Interface (ABI) on RHEL.

Lā€™ABI of RHEL is a set of rules that define how applications and libraries must interact at a binary level with the operating system.

The approach chosen by AlmaLinux ensures the possibility of using software designed for RHEL without having to deal with compatibility problems, while maintaining broad flexibility in the development and updating of the distribution. AlmaLinux, in fact, makes available patch e updates completely independently of RHEL.

In short, AlmaLinux developers are not even bound to following a “bug-for-bug” compatibility line with RHEL: for example, corrections can be accepted outside the Red Hat release cycle.

What’s new in AlmaLinux 9.4

Demonstrating the speed and stability of the project, AlmaLinux 9.4 arrives ā€“ as highlighted earlier ā€“ a week after the launch of RHEL 9.4.

Some of the novelty introduced in AlmaLinux 9.4 concern improvements to security and data protection, as well as updates related to console Web and to system roles that automate some operations and promote consistency in complex environments.

Among the new features there are also new system roles that allow the creation and management of snapshot of the Logical Volume Manager (LVM) to improve data backup and recovery processes. Additionally, improvements have been made to the availability and reliability of the system, making it easier recovery operations and enhancing virtual machine snapshot capabilities in hybrid cloud environments.

A significant change concerns the driver management of devices no longer supported by Red Hat. AlmaLinux continues to embrace their use and does not deviate from the list of devices that the AlmaLinux community still used. AlmaLinux 9.4 also includes support for various devices previously disabled in RHEL, such as controller RAID from various manufacturers and network adapters.

The update just presented and available here for download, not only improves the performance and the scalability of the system but also offers an option to extend the life of older servers, helping to keep costs low.
