Some docker success! I have little time, so I copied and pasted from https://core0.staticworld.net/assets/media-resource/16373/ifw_dd_docker.pdf (which is out of date already) so used the script name ‘startapache’ but I don’t have internizzle access atm so I just made the script echo ‘your mom’

That’s amazing in its own right (a container that looks like a machine, running on my machine!) but the next steps, I was able to save a copy of the machine and run a new instance of the machine, which still had the entire state of the machine inside it (well, the history file, at least).

Very very interesting! (N.B. from the output of the docker ps -a commands below, I have cropped the empty PORTS column to help the output fit more easily without added soft linebreaks.)
