In this episode of Linux Server Admin with Fexingo, Lucas and Luna dive into etckeeper, a lightweight tool that automatically version-controls your /etc directory with Git. They walk through installation, configuration, and a real-world scenario where etckeeper saved a sysadmin after a botched Nginx config edit. You'll learn how to set it up in under five minutes, how it integrates with package managers, and why it's a smarter safety net than manual backups or ad-hoc snapshots. Perfect for anyone running production Linux servers who wants to track every change to critical config files without extra overhead. Plus, a quick case on rolling back a broken SSH config after a remote reboot. No fluff, just practical server engineering.
