[Nut-upsuser] reboot of nut managment node resets Tripplite SMX1000LCD

[Roger Price]

I'm assuming that the results you report here correspond to the unexpected 
UPS shutdown on a re-booting Ubuntu box.

I do not see any delayed UPS shutdown messages.  How do you call for a UPS 
shutdown?

I do not see any command to stop nut-server.  Did you stop NUT before rebooting 
as suggested?

This is aside from your unwanted UPS shutdown problem.  I do not understand why 
you call "reboot" when you have already asked "shutdown" to reboot.

I would expect to see

   nut-driver.service   loaded active running   Network UPS Tools - power device driver controller
   nut-monitor.service  loaded active running   Network UPS Tools - power device monitor and shutdown controller
   nut-server.service   loaded active running   Network UPS Tools - power devices information server

What happened to upsmon?
