I've recently started using yadm, which is a light abstraction on top of git. One big reason - "Alternate Files" support - which makes it easy to have MacOS and Linux binaries for the same tools, along with the rest of my shell setup, in one Git repo.

Same here. New machine? Add a remote, checkout master.
