+## OpenMowerOS legacy

+For the legacy OpenMowerOS image you need to create a systemd service. Create a file at `/etc/systemd/system/openmower-app.service` with the following content:
+
+```
+[Unit]
+Description=Podman container - openmower-app.service
+Documentation=man:podman-generate-systemd(1)
+Wants=network.target
+After=network-online.target NetworkManager.service
+StartLimitInterval=120

+Restart=always
+RestartSec=15s
