Hah! Thanks for whomever posted this. This is my little baby/project and I'd like to share a little about it... Quite some years ago (before all this AI Hype) I ventured on trying to deeply understand how Linux containers worked. At first I built a shell script called `box` that used the Busybox `unshare` utility to create little isolated namespaces/cgroups where you could "box" your little program on the root file-system. Later on I decided to write box in Go.

box now is basically a fully capable lightweight daemon-less container runtime, much like podman (but no rootless, not yet). Along with another project I also wrote called sshbox that is basically an SSH reverse prox; are what powered mbox.blue

mbox.blue is basically an experimental shared Linux system based around the core idea of persisetnt containers. All home grown.
