I am a little bit confused about RancherOS objective, I can guess it is really useful as a tinny OS you can use to run containers. The first time I hear bout it I thought in something like (semi)automatic way of registering your devices with your Rancher Server. Why RancherOS does not directly include a Rancher Agent? What I am trying to do is to have an .img file that you burn in your device and this automatically appears in your Rancher server (passing some configuration with cloud-config is ok). I am going in the wrong direction with RancherOS?
