Thanks! I think that's a great idea. Containers are nice, but there's nothing quite like a "real" VM system in terms of learning + developing, and they can be very cheap if you're OK with the performance hit from nested virtualization :)

Another idea I had is to customize the rootfs. It boots Alpine right now, but should be trivial to change it to anything else (and it only takes ~5 seconds to build!).
