[Xymon] Starting Xymon via init script no environment variables

[Michael Beatty]

Well... I figured out it has to do with how sudo invokes the 
environment.  I'm pretty sure there is a parameter I could supply to 
sudo to bring in the environment, but it was just as easy to switch from 
sudo to su.

I changed my commands to:
su - xymon -c "/home/xymon/client/runclient.sh start"
and it works now.

If anyone who understands this better than me understands why, I would 
appreciate an explanation.
