            this more than once
          --download-only - only download packages - do not run the

Cannot find any package matching --exclude=rhythmbox available to be
updated.
Cannot find any package matching --exclude=nautilus-media available to
be updated.
Cannot find any package matching --exclude=gnome-media available to be

No actions to take

WTF!  Usage tells me I can exclude packages with --exclude=some_pkg_name
but that switch seems to be unknown to yum.
