Yeah I appreciate this. And since I'm a researcher rather than an engineer I'm also not forced to get on the threadmill. But like I said, I do see some value in using Docker as a tool to let a bunch of researchers run wild as semi-trusted superusers (by "semi-trusted" I mean we can be trusted not to purposefully do evil, but not trusted not to accidentlaly step on each others' fet). So I'd still like to learn a bit :-)
