AWS GreenGrass Components - run on device start up

Hello,

I have an IoT device which is shutdown overnight due to customer requirements, and is restarted in the morning.

Currently the service used to operate the device is started using a systemd service, this works, but is not the solution we are after.

I am looking at using Greengrass components to deploy the service to the device, and monitor the service (Long lived service which needs to always be running/restart if failed), but I am struggling to find any resources on how/if components run on start up? I know the greengrass.service is run on start up, so I am wondering if i need to set anything in the component recipe? The device also may not have internet access on start up, i.e. it must start the service without an internet connection.

Thanks heaps, Matt
