Good to know.

See 'man 8 blazer' for a list of recognized options. The above one  
isn't one of them, so specifying it won't make the driver shutdown any  
sooner. The clone driver which can be run on top of any other driver  
will allow you to shutdown the loads based on battery.charge and  
battery.runtime. See 'man 8 clone'.
