I've written about half a dozen .service files for the different parts that make up the system I'm working on. It's useful to be able to start the whole system piecemeal but I'd also like to have a single unit that starts the whole system in one call to systemctl.
What's the best way to do this?

You want a target-type unit, with all the service units listed as
Wants=dependencies. Then you start it usingsystemctl start unitname.target. (Make sure not to usesystemctl isolatehere; that will shut down everything except what's in your services' dependency tree, which you presumably don't want.)
