[Nut-upsuser] NUT with Cyber Power 700 AVR

[Rob Donovan]

I'll add that when I tested the restart script/binary it worked 
perfectly.  However, I tested it by giving nut a bash shell in 
/etc/passwd, then doing su nut, and running /sbin/upsschedcmd restart 
from a bash shell.  After that I reset nut's shell to /bin/false.  The 
failure above to stop the upsmon owned by root looks suspiciously to me 
like the setuid isn't working properly in the running system.  If I fix 
it I'll post here.
