This won't work. In order to send a poweroff command to the UPS, the  
drivers must be restarted from scratch. Therefor you must run 'service  
nut stop' before doing that, otherwise the backgrounded drivers will  
not have exited.

It also is a good idea to put a 'sleep 2' between the two commands, to  
give the drivers some time to respond to the KILL signal they receive:

     echo "Stopping nut service"
     service nut stop
     sleep 2
     echo "Initiating UPS Powerdown Sequence"
     /sbin/upsdrvctl shutdown
