this is a feature request:
It would be really nice to be able to manage Net-Boot (RancherOS) and configuration of BareMetal machines via Rancher Server.
There are some Docker containers to NetBoot RancherOS. Such capabilities integrated in Rancher Server, along with cloud-config & key management would be a fantastic addion.
CoreOS offers Matchbox & Ignition for similar purposes, but with very little comfort.
