Sounds like you ramped up pretty quickly! Were you pretty familiar with the terminal beforehand or just jumping in?
I’m chronically unable to finish projects but with such a fantastic tool maybe this one is the one? I’ll try follow up if get something going.
Does ublue have any plans to do variants of Fedora IoT? CoreOS seems more targeted for cloud than home servers. The ignition file is a benefit if you want to spin up hundreds of servers but a bit of a hindrance if you just starting out at home with a machine or two.
If they are just installing to a single machine and don’t need drivers or kernel mods I’d suggest IoT over bothering with anything CoreOS.
