I understand the need to install rather than update kernels.  Yum does
this automatically for kernel, kernel-smp, kernel-bigmem,
kernel-enterprise, kernel-debug, and kernel-unsupported.

Wait...I had the files backwards.  The NEW version of the yum.conf has
the installonly line I was wondering about.  I thought it was something
that I might have done previously, but apparently it's a new default
setting in the yum package.  In that case, I'll just use the new one.

Sorry for the confusion.
