Configure dnf-automatic on Rocky Linux to apply security updates automatically via systemd timers, with security-only upgrade_type, verification checks, and limited rollback via DNF history.
Learn how Rocky Linux achieves 1:1 binary compatibility with RHEL through source rebuilds, and see a step‑by‑step example of migrating a CentOS 8 system to Rocky Linux 8 while keeping existing configurations intact.
Enable FIPS 140-2 validated cryptography on Rocky Linux 9 by installing dracut-fips, rebuilding the initramfs, adding fips=1 to GRUB, and verifying with /proc/sys/crypto/fips_enabled.
CentOS Linux is EOL. Learn how to choose between CentOS Stream, Rocky Linux, AlmaLinux, or RHEL based on your stability needs, and how to verify your current distribution.
Rocky Linux uses XFS for its root filesystem because Allocation Groups and delayed allocation scale well under concurrent I/O. Learn how to verify, grow it online via LVM, and avoid the no-shrink trap.
Rocky Linux defaults to XFS on LVM — great for online growth and parallel I/O, but shrinking is impossible. Here's how to plan around that one-way door and grow volumes live.
A practical guide to configuring and verifying DNF GPG signature enforcement and metadata expiration in Rocky Linux 8 and 9, with concrete commands, security considerations, and recovery steps for common failures.
CentOS 8 is EOL. Compare CentOS Stream, Rocky Linux, and AlmaLinux, then follow a validated in-place migration to Rocky Linux with integrity checks.
Rocky Linux's Peridot build system replaces CBS with a pluggable Go pipeline that enforces reproducible builds via signed BuildSet manifests, modular composes, and automatic SPDX SBOMs — enabling a 24-hour security-update SLA through gated promotions.
