Any links for more info about containers vs VM there? The article just says:
"That’s because Google is going to start shipping Chrome OS with a custom virtual machine that runs Debian Stretch, the current stable version of the operating system."
I have been using this on my pixelbook and, unless I am wildly mistaken, it's generating an LXC container. Android apps for instance all run inside a single container for them as well
The container itself is running Debian Stretch. However, for someone not using this it can be easily misinterpreted to mean a VM. Functionally it's not much different.
