Ever since it was released as a successor to CentOS 8 which was prematurely discontinued, Rocky Linux has proven to be a reliable, and formidable operating system for handling enterprise-grade workloads.
It’s completely free and open-source and 100% bug-to-bug compatible with Red Hat Enterprise Linux. It provides rock-solid stability for enterprise workloads, regular updates, and a 10-year support cycle.
Rocky Linux 9 is the latest release and was made available on July 14. 2022, and users can now download the ISO image and install it on their servers. It ships with a number of improvements and enhancements which we shall look at shortly.

Rocky Linux 9.0 has seen a couple of security most notably:
- SELinux Improvements – Memory overhead, loading time, and performance have been substantially improved.
- OpenSSH 8.7 p 1 is the latest version. Notable improvements include the replacement of SCP/RCP protocol with SFTP protocol which offers solid encryption and more predictable handling of filenames.
- OpenSSL 3.0.1 is the newest version. It provides improvements such as a new versioning scheme, support for new protocols & algorithms, and an improved HTTP(S) client among many others.
- Deprecation of SHA-1 message digest for cryptographic purposes. The hash functions associated with SHA-1 are no longer considered secure.
The XFS filesystem now supports Direct Access (DAX) operations allowing direct access to byte-addressable persistent memory. This helps to avoid the latency of leveraging traditional block I/O conventions. Additionally, NGS introduces an “eager write” mount option for minimizing latency.
In Rocky Linux 9, GNOME 40 is the default desktop environment. GNOME 40 is freshly redesigned to provide a sleeker UI for a desktop operating system. Now more than ever, it’s much easier to launch your applications and arrange your personal workspace.
Notable improvements for desktop usage include:
- Fractional display scaling.
- Ability to group applications into folders using the drag and drop method thanks to the revamped ‘Activities‘ application.
- Ability to mute notifications by toggling on “Do not disturb” which appears as a separate button in the notification.
- The different refresh rates for every screen.
