#  arch: x86_64          # default architecture
#  md-raid-dev:          # mdadm device eg: /dev/md126
#  deploy_host:          # node hosting pxelinux.cfg configurations
#  ipmitool_host:        # node with ipmitool and mgmt vlan access
#  pxe_bootdev: eth0     # device used as bootdev and first interface configured
#  rhcos_install_img_url: # Where to grab rhcos install http://<host>/<path>/rhcos/rhcos-4.3.8-x86_64-metal.x86_64.raw.gz
#  rhcos_ignition_file_url: # where to find ignition file http://<host>/config/rhcos/bootstrap.ign #to be modified based on group or host level, for bootstrap, master, etc
