I have no idea what I'm doing so it's a night-and-day kernel programming experience to be able to commit container state; conduct experiments; reset back to a clean state; in one command.

Another key element that makes this so useful to me is that I work on a macbook (gasp), and hacky stuff I have to do in that context is the first source of blame when e.g. a header gives weird type issues.

Thank you so much for putting this together.
