EliotOS is minimal Linux Operating System, built with Linuxkit, which contains only minimal components to run Eliot.
At the moment, there's pre-built image for RaspberryPI 3 available.
linuxkit build rpi3.yml
You can run EliotOS locally with linuxkit
but keep in mind that the environment is amd64 not arm64 so container images what work in the local development environment, are not suitable for RaspberryPI use.
sudo linuxkit run hyperkit -cpus 4 -mem "1024" -disk size=10G -networking vmnet rpi3
