The first time you run yum it downloads package headers for *all*
available packages from your list of repositories.  This doesn't
change/install anything new.  Then it compares available versions
to your installed rpms and will offer to download/install any
newer packages.  You get a chance at that point to decline.
Subsequent runs will only download newer headers for the comparison.
It is usually safe to add one outside repository because they are all
compatible with the base release.  Sometimes you will see conflicts
if you add multiple outside repositories because they aren't all
compatible with each other.  The outside repositories offer packages
not included in the base release and sometimes newer versions of
packages than fedora has.
