Really fun, kind of trains you to when the situation happens IRL, whether you're thinking about how to escape a shell or if you really did it by mistake.

I love showing this screenshot to people: https://imgur.com/a/ziHqJxB. I was having problems trying to create a jailed shell, so I decided to bind mount /bin. That of course was a bad idea. I gave up and rm -rf'd the mountpoint without unmounting it. The screenshot has the serial logs from after that :P.

I had a good time enjoying my stupidity.
