I can't test Systemd, but I've installed Gremlin Server as a service and
that worked like a charm. Manual starts / restarts / stops /status requests
worked as expected. Killing the process didn't lead to any unexpected behavior.
Next I installed the service as a real system service (I may have
overlooked it, but I believe this is not mentioned in the docs):
```
daniel@cube ~ $ sudo update-rc.d -f gremlin-server defaults

```
Then I rebooted my system and Gremlin Server started right away. Great!
Finally I removed the system service:
```

That's it. No surprises, everything's working well. Nothing to add here,
except ...

> Components: server
> Affects Versions: 3.0.2-incubating
> Reporter: Jeremy Hanna
> Assignee: Dylan Millikin
> Priority: Minor
> Labels: breaking
>
> Based on this discussion, it looks like there was an example from [~dkuppitz]
> on how to create a gremlin server service on linux:
> https://groups.google.com/forum/#!msg/gremlin-users/uA48IQ3YJcw/4KnUKIS8HI4J
> Here is a link to the gist for the service:
> https://gist.github.com/dkuppitz/20bda51e3465a612cd9b
> I think it would be great to include this or a way to daemonize the server
> into the tinkerpop distribution.
