Description of problem:

I was trying to track down a problem that caused excessive CPU usage on a friend
s machine and I discovered the following:

/etc/X11/prefdm contains 

# shut down any graphical boot that might exist
if [ -x /usr/bin/rhgb-client ]; then
    /usr/bin/rhgb-client -quit
fi

However the valid switch to quit is -q or --quit, which probably means that it
does quit but it should probably be changed just for correctness.

Version-Release number of selected component (if applicable):
initscripts-8.34-1

How reproducible:
