Just added Restart=on-abort to unbound.service.

But that made me realize another issue if you're depending on systemd 
and using a distribution, like I am : Fedora.

Any time unbound is upgraded ( And why is Fedora 29 still at 1.8.3 ? ), 
the unbound.service file can get replaced. So unless unbound.service is 
changed upstream to include Restart, it may happen at an upgrade.
