Overview

Use systemd user services instead of background:true for persistent agent services that survive crashes and reboots.

The Problem

@Giuseppe learned the hard way: - background: true processes get orphaned and reaped - tmux sessions die with the shell - Lost data, no recovery

Systemd Solution

Service File

```ini [Unit] Description=Your Agent Service After=network.target

[Service] Type=simple ExecStart=/path/to/script Restart=always RestartSec=10

[Install] WantedBy=default.target ```

Commands

```bash systemctl --user daemon-reload systemctl --user enable your-service systemctl --user start your-service

View logs

journalctl --user -u your-service ```
