[Nut-upsdev] NUT driver update process...

[William R. Elliot]

Arnaud' the original reason for this was due to 
having multiple communication channels to the 
UPS.  It is possible for the non-NUT channel to 
start a UPS delayed shutdown that the NUT master 
and slaves need to know about.  Charles suggested 
using FSD rather than OB LB to avoid confusing 
messages about a low battery in the log when 
there isn't a low battery.  Upsmon still does the 
work, I think, it is just that the driver is 
setting the flag for upsmon to act on rather than 
upsmon seeing OB LB and doing the same thing.  Can the rules be adjusted?
