Debian vs Rocky Linux

Debian is a free operating system created by the Debian Project, an association of individuals. Its systems use either the Linux or FreeBSD kernel and include more than 70,000 packages managed with APT, plus tools for managing packages across computers. Installation choices include a live system with the Calamares installer and an installer with options such as automated network installation. Debian supports architectures including amd64, i386, ARM variants, POWER, IBM System Z and RISC-V. Users can choose stable, testing or unstable releases, upgrade to a new release or update individual packages. Debian coordinates security advisories with other free software vendors, and many advisories are published the day a vulnerability becomes public. Its free Long Term Support extends stable releases to at least five years; commercial Extended LTS covers a limited set of packages beyond that. Official cloud images are available, and Debian can also run in virtual machines or containers. Help is available through documentation, mailing lists, IRC and consultants. Debian notes that hardware from companies that do not publish specifications may not work with GNU/Linux.

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.
