On the DVD

This first release of Rocky Linux is "a community enterprise operating system designed to be 100% bug-for-bug compatible" with Red Hat Enterprise Linux 8.4 [1]. The Rocky Enterprise Software Foundation (RESF) strategy is to maintain a downstream build, which means releases are built after they have been added by the upstream vendor, not before, as with CentOS. The minimal edition on this DVD is intended for servers and will not include rsyslog.service or /var/log/messages, although the rsyslog package can be installed from the Rocky Linux App-Stream repository immediately after reboot.

Rocky Linux also features:

• The migrate2rocky tool, which lets you convert to Rocky Linux 8.4 from other Enterprise Linux systems.
• Multiprotocol label switching (MPLS), an in-kernel data-forwarding mechanism to route traffic flow across enterprise networks.
• Proactive memory compaction to reduce latency.
• Slab memory controller, which switches memory accounting from the page level to the object level.
• In-container clock adjustments.
• Persistent Pacemaker resource agent.
• Ansible modules for automated management of RBAC.
