Frequently Asked Questions

What is a systemd service unit file?▼
A systemd service unit file is a configuration file (ending in .service) that tells systemd how to manage a background service or daemon on Linux. It defines how the service starts, stops, restarts, what user it runs as, its dependencies, and security restrictions. Unit files are stored in /etc/systemd/system/ for admin-created services.
What is the difference between systemd service types?▼
The Type= directive controls how systemd tracks the service. "simple" (default) means the ExecStart process is the main process. "forking" means the process forks and the parent exits (traditional daemons). "oneshot" runs a command and exits (for scripts). "notify" means the process sends a readiness notification to systemd via sd_notify().
How do I enable and start a systemd service?▼
After placing your .service file in /etc/systemd/system/, run "sudo systemctl daemon-reload" to reload unit files, then "sudo systemctl enable myservice" to start it on boot, and "sudo systemctl start myservice" to start it immediately. Use "systemctl status myservice" to check its state and "journalctl -u myservice" to view logs.
What systemd security options should I use?▼
For hardened services, enable ProtectSystem=strict (read-only filesystem), PrivateTmp=true (isolated /tmp), NoNewPrivileges=true (prevent privilege escalation), ProtectHome=true (no access to /home), and ReadOnlyPaths=/ with ReadWritePaths for specific directories. Also consider PrivateDevices, ProtectKernelTunables, and RestrictNamespaces.
