[Nut-upsuser] Shutdown problem with Geek Squad GS1285U

[Gary Redden]

Nut will monitor the ups and shutdown Linux when the ups goes to low 
battery as it should. But the UPS is not shut down so the system will 
restart when the power is restored. If I switch the UPS off , restore 
power and switch the UPS on the system will restart. I have not been 
able to get nut to switch the UPS off after it brings the system down. I 
can get the UPS to switch off  with upscmd load.off. So the UPS can be 
controlled. Here is my SHUTDOWNCMD:
SHUTDOWNCMD "/sbin/shutdown now -P"
I also tried:
SHUTDOWNCMD "/sbin/shutdown now -h"
I found this script in /etc/init.d/nut and changed the paths to upsd and 
upsmon and used it.
#! /bin/sh

Since I do not have much knowledge on how the Linux  system boots and 
shutdown I have spent the last several days searching for how the scrips 
/etc/init.d are supposed to work but every thing I have found is a 
little different than what I find on my Ubuntu system. Does this script 
ever get called with poweroff?
