Solved: The Automation That Ruined Manual Work For Me Forever

🚀 Executive Summary TL;DR: A critical production server crash due to a full disk from uncleaned temporary files highlighted the urgent need for robust automation in system housekeeping. The article details a progression from emergency cron jobs to modern solutions like systemd-tmpfiles and logrotate, ultimately advocating for ephemeral infrastructure to eliminate disk creep entirely. 🎯 Key Takeaways Systemic disk management is crucial, as relying on developers for perfect self-cleaning code is insufficient; active, automated housekeeping is required for finite disk resources. Modern Linux systems offer superior, declarative tools like systemd-tmpfiles for managing temporary directories and logrotate for automated log file rotation, compression, and deletion. Adopting an ephemeral infrastructure model, where servers are treated as disposable and regularly replaced from ‘Golden AMIs,’ completely eliminates the problem of disk creep and local state accumulation.
