[Nut-upsuser] I am a bit confused

[durwin at mgtsciences.com]

I have read the shutdown.txt in the docs directory.  It says that after 
upsmon calls the shutdown command init takes over.  This I understand 
clearly.  However, step 8.

8. init then runs your shutdown script.  This checks for the
   POWERDOWNFLAG, finds it, and tells the UPS driver(s) to power off
   the load.

Since init is shuting down the system, why is the POWERDOWNFLAG needed? 
Why do I need a shutdown script?  init is shuting down everything!
