systemd service descriptions end up in the journal as "Starting DESCRIPTION" and "Stopping DESCRIPTION". The current description sounds weird in that context. The upstream systemd unit description has the description "Bumblebee C Daemon", but that isn't descriptive enough, IMHO. How about  something like "Bumblebee Hybrid Graphics Switcher"?

The point about "managing Optimus video card" could be good to have in the description of the ```hardware.bumblebee.enable``` option.

Upstream unit file also has ```CPUSchedulingPolicy=idle```.
