Files should be installed into /usr/lib/systemd/user/
Unlike the existing service file, this one configures deluge to run as a
desktop session user. The difference between the services files is the
use of multi-user.target in system service which does not exist for user
services so requires default.target.
Including the Slice indicates to the service manager that this is a
background service. This can be used to handle OOM situations, or
prioritising foreground processes. There's no equivalent for system
services.
