[Nut-upsuser] Shutdown problem with Geek Squad GS1285U

[Peter Selinger]

Hi Gary,

I am no good at reading kernel logs; these are Greek to me. 

The normal sequence is that upsd, upsmon, and the driver are all
stopped. Then 'upsdrvctl shutdown' is called as a standalone program
at the very end to turn off the power. (Neither a daemon nor a monitor
are required at that time).

There could be several reasons this fails. 

* perhaps your binaries are in /usr/local/bin, and your /usr/local
  partition has already been unmounted. In this case, you need to put
  the binaries in the root partition somewhere (/usr/bin or /bin). 

* perhaps your USB filesystem is in /proc/bus/usb, and /proc/bus/usb
  has already been unmounted prior to shutdown. In this case,
  newhidups will be unable to talk to your UPS. You would need to
  mount it again before calling upsdrvctl: 
  mount -t usbfs usbfs /proc/bus/usb

For testing purposes, you can replace the call to "upsdrvctl shutdown"
by a call to "/bin/sh", which will drop you to a shell at the right
moment in the shutdown sequence. You can then experiment and see what
you need to call to shutdown the system.
