How to enable systemd to run in the background?
And enable it (which will run it at boot, per the unit config): And then start the service: The service should now run in the background, and you can check journalctl to watch its output.

What can I use systemd for in Linux?
Systemd is used for a lot of things in Linux; each object it manages is called a Unit, and have a corresponding “Unit File” defining what they are. These can be simple services like nginx or MySQL, but they can also be things like mount points, devices, sockets, and lots of other under-the-hood stuff, all managed by systemd.
