It can also boot on the Nintendo Switch: <a href="https://twitter.com/imbushuo/status/1314487034040311808" rel="nofollow">https://twitter.com/imbushuo/status/1314487034040311808</a>
This might be a good way to get a CTF/pentesting lab up and running on a RPi. I've been looking for a good way to do that where I can do my CTF tests remotely on my homelab.
This is an awesome PoC for expanding on to ARM CPUs but i don't see the Pi being an efficient virtualization platform. Once you introduce the CPU/memory overhead of 2-3 vms will quickly degrade any meaningful CPU performance.
