There goes my weekend to investigate...
I am sorry for that 😆 but to be honest I have also spent good amounts of past weekends diving into this topic.

I had great hopes for CoreOS
Yes, fcos is actually the successor of this, but has meanwhile gotten a bunch of new components such as the usage of ignition instead of cloud-init.
I forgot to mention one other cool this about fcos. Once you have generated your ignition file you can use the coreos-installer to bake it into an iso file. I don't know if there is an easier way to generate a software appliance out there. And inside of the ignition file you can merge or even completely replace it at runtime with files it can fetch from the internet at runtime.
https://major.io/p/coreos-as-pet/ is another blog that highlights some of the potentials of fcos outside of the usual Kubernetes usage.
