[quoted lines by Mike Gorse on 2016/01/08 at 13:26 -0500]

I decided to tackle systemd this afternoon. I now have multiple brlttys 
supported via systemd's instantiation (or template) feature. I also have the 
correct one stopping when the device disappears. The braille device is used as 
the instance name, for example:

   systemctl start brltty@usb:whatever

The remaining problem is how the simple brltty service unit should start an 
instance without duplicating most of the instance unit. An empty instance name 
isn't valid but I don't want a specific device to be specified. In other words, 
I'd like a way where %i evaluates to an empty string. Does anyone know how to 
do that? Does anyone know of an existing systemd example which has both a basic 
and an instance service unit?
