I've done something that sounds similar with bash scripts and systemd path units. Every time I modify a configuration file from any of a number of paths I'm interested in versioning, I get a prompt to supply an optional commit message, and the change is automatically committed and pushed to remote. It's not the whole file system, but the commit messages on configuration file changes have come in handy at least once.
