The responses were to change the value of "tokeep". You can also
change "enable=1" to "enable=0" or totally remove the installonlyn
plugin.  (Go to the bottom of
http://docs.fedoraproject.org/yum/en/sn-yum-customizing.html for
details.)

After a quick exchange with the Red Hat QA/developer,
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=237203 ,  I
realized the default installation of the installonlyn plugin is the
problem.  RHEL installations need the plugin. Fedora Core users do
not. Why? Because the lifespan of a FC distro is short (approximately
18 months). The number of kernel updates within that time is not
large. The majority of FC'ers will have upgraded to the next FC
release before their disk runs out of space from kernel installs. Just
disable or remove installonlyn. You are better off without it.
