Description of problem:
the use of nut-0.45.4 as changed
The main change is upsmon running as nobody, and cannot read files in /etc/ups 
and create /var/run/upssched.pipe


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install nut as a master
2. Setup a timer
3. start the ups service
3. unplug the power cord of the ups.


Actual Results:  
1. upsmon is started as nobody
2. upsmon don't start properly because it cannot read /etc/ups/upssched.conf 
(use upsmon -d in init.d to enable debuging in syslog)
3. upssched-cmd is not started because upsmon cannot 
create /var/run/upssched.pipe



Additional info:

The solution is to use the -p swith with upsmon in /etc/init.d to not start 
using an unprivileged uid. ( man upsmon )
And for the setup of a timer dont forget to uncomment PIPEFN in 
/etc/ups/upssched.conf

0.45.4 use a noew configuration file 

An better solution could be to use to nut 1.2 !
