Inspired by @bycx I started looking into CoreOS which seems like a good OS for my home cluster (immutable, more lightweight than Debian, easier to maintain).
I'm starting with a simple process - installing from flash drive and providing the installer with prepared Ignition config file (generated with Butane). The process went through but upon booting I get "unsupported config version". And indeed, the config doesn't validate with ignition-validate because. As simple as this is, I cannot make it work. What am I overlooking?
