Free distribution source code based on the Red Hat Enterprise Linux 9 (RHEL 9) operating system family,Rocky Linux 9.0 features GNOME 40 as the default desktop environment, support for DAX operations in XFS for direct access to byte-addressable persistent memory, and the “eager write” mount option in NFS to help reduce latency.
In terms of security, the Rocky Linux 9.0 series disables root user authentication using a password via SSH by default to prevent attackers from using brute force password attacks to gain access, and supports OpenSSL 3.0.
