I didn't discover Chezmoi until seeing this thread (sigh). I developed a tool, filetailor, with an almost identical goal (dotfile management while accounting for differences across machines). It uses Python and YAML, but from what I can tell is similar in concept to Chezmoi.
One thing I like about filetailor I didn't see in Chezmoi was the ability to surround code with a comment specifying which machines it should be commented/uncommented for. It's easier than templates in some situations.
It works great, but there's probably tons of bugs that occur when used by someone other than me. I don't have a CS background and this was my first big hobby project.
