Converting Butane to Ignition on Boot

We’ve received anecdotal evidence over the years that the transpilation step where you must convert a Butane YAML configuration into Ignition JSON before staring your CoreOS instance is a pain for users to understand and implement. CoreOS developers also feel this pain at times.

What if you could feed either a Butane YAML config or an Ignition JSON config to your instance and it would just do the right thing regardless?

I did a proof of concept of this and showed a short demo during an internal team meeting last week. Check it out (below) and let us know what you think over in https://github.com/coreos/fedora-coreos-tracker/issues/2006
