So I recently picked up a shiny new MacBook. This was not my first time around this particular wheel. I’ve enjoyed them for professional and personal use for many years. This time I thought I’d try a rather tidier approach to shell setup and started with a blank slate and — inspired by a Jess Frazelle talk I enjoyed at Kiwicon some years ago — a goal of running a lot more software in Docker containers to isolate it at least a little bit from my $HOME and precious/private data.
