Adding NTP and other configuration items to k3os after install

Hello, I keep discovering things I should have configured with my cloud init during the install on k3os and wondering how I can just configure these on the install. I see from the documentation the below path but I don’t see a config file present. Do I just create a file and populate it with what is needed? Thanks

/var/lib/rancher/k3os/config.yaml or config.d/*

Derp, just create the file and it will pick up the config.
