CoreOS doesn't use cloud-init like the rest of the world, but a custom system called ignition that requires compiling. A host program called "butane" converts the cidata yaml, to a host config file called config.ign (which is in json). Signed-off-by: Anders F Björklund <anders.f.bjorklund@gmail.com>
This doesn't actually start any services, but waiting for the nerdctl user to run `containerd-rootless-setuptool.sh install`. Alternatively to start up the installed system containerd.service, replacing the one from docker, and run `sudo nerdctl` with it. Signed-off-by: Anders F Björklund <anders.f.bjorklund@gmail.com>
It is only possible to lint the executed template, not the raw "yaml". But it is syntax-checked by butane --strict anyway, so is not needed. Signed-off-by: Anders F Björklund <anders.f.bjorklund@gmail.com>
This uses ignition and prefix, to support Flatcar Container Linux It is the continuation of the original CoreOS, before Fedora CoreOS Signed-off-by: Anders F Björklund <anders.f.bjorklund@gmail.com>

Requirements:
Squashed and rebased the old PRs, for re-evaluation.
Add example for Fedora CoreOS, running ignition not cloud-init #1653Add flatcar experimental example, another with coreos ignition #1657Needs testing, I have only updated the numbers and checksums but haven't verified if it actually works or not.
Running an immutable OS (for Lima) is still annoying, the scripts don't work and there are reboots all the time.
It runs Docker by default (enabled), and Podman on demand (disabled)
Note: CoreOS Container Linux is a common ancestor for both FCOS and Flatcar.
