Why use a systemd service unit over screen, tmux, or nohup?
Automatic Host Rebootssystemd units automatically restart your daemons whenever your virtual machine or server reboots, ensuring zero manual intervention.
Crash Recovery & WatchdogsConfigured auto-restart policies bring failing applications back to life within seconds with backoff limits to prevent CPU runaway.
Unified Structured Loggingstdout and stderr are ingested automatically into systemd journald with rotation, log limits, timestamps, and syslog filtering.
