Hey, @PHPGangsta, thanks for your PR!

I'm a bit hesistant about merging it, because it assumes that unbound is also installed on the same machine and configuration files are stored in the /etc/unbound (because, for example, unbound by itself uses /usr/local/etc/unbound root by default unless it is overridden by the OS-specific configuration.

This systemd should probably also have a dependency on the unbound unit too? I'm not sure about this one.

Yet, it would be great to have some unit file as an example, do you think we should tweak it maybe and add a little example on how to override the ExecStart value?
