src is a cute wrapper for rcs, but it has all of the same limitations of rcs, plus a few extra, so I hope you'd consider sccs/cssc if you wanted something "like rcs" but not. fossil is also a really interesting choice for an "easy setup" version control system, and it's definitely worth considering if you're looking at sccs/cssc: I've used it to log configuration changes for an application, the "push" functionality to centralise changes from tenants, and then I can store issues/tickets (and other metadata) on the configuration changes centrally.
