Arch Linux: Arch and CachyOS Administration

Administer Arch Linux and Arch-style systems without falling into rolling-release footguns. Focus on vanilla Arch first, then layer in CachyOS behavior, paru workflow, systemd-native service management, boot recovery, kernel handling, and derivative-specific cautions.

Versions worth pinning (September 2026):

Only pin versions here when they materially affect compatibility or troubleshooting shape. For ordinary rolling packages, prefer the current repo state over stale version tables. Versions below are upstream component versions; distro package release suffixes and epochs are repository-specific. Check the enabled Arch or CachyOS repository before comparing builds.
