Creator of RancherOS here. Thanks for the interest in our tiny distro. RancherOS was created the beginning of 2015 and at the time was quite a novel concept. We strived to not just use container technologies in a Linux distro but actually package everything as standard Docker containers. Fast forward two years, what we were doing back then is now becoming the accepted practice. Most major distro are adopting more container packaging approaches in the form of flatpak, snap, and containerd. RancherOS 1.0 LTS was just released a couple weeks back and we have started development on 2.0. 1.0 was a bit ahead of the time and honestly had to employ a lot of technics to make it work that we didn't like. With 2.0 we will shift the focus from Docker to containerd, OCI, and LinuxKit which will allow a much cleaner design.
We released some versions for ARM but in the end ARM requires too much effort to support right now. As ARM64 matures and Docker gets full multi arch image support we'll revisit this.
