Red Hat vs Rocky Linux

Red Hat has no write-up on Specifiction yet; its figures are above.

Rocky Linux is a free, open-source enterprise operating system designed for bug-for-bug compatibility with Red Hat Enterprise Linux. It rebuilds sources directly from Red Hat Enterprise Linux and supports migration from other Enterprise Linux distributions. The project describes it as production ready and gives major releases a 10-year support lifecycle: five years of active support followed by five years of security support. Only the latest minor release is supported. Images are available for physical installation, cloud platforms, containers, and Windows Subsystem for Linux, among other formats. Rocky Linux 10 supports x86-64-v3, riscv64, aarch64, ppc64le, and s390x, though architecture support varies by release. It uses DNF for package management and upgrade commands, with RPM packages in a RHEL-compatible software environment. Rocky Linux 10 requires x86-64-v3 on x86_64 and omits 32-bit compatibility packages. Major-version upgrades are not supported, so moving to Rocky Linux 10 requires a fresh installation. Community and commercial support options are listed.
