CentOS - Jul 2007 - Is installonly option needed?

I just updated to the most recent version of yum.  I noticed that my
yum.conf file had changed.

The old one has:
installonlypkgs=kernel kernel-smp kernel-devel kernel-smp-devel
kernel-largesmp kernel-largesmp-devel kernel-hugemem kernel-hugemem-devel

The new one does not have this option listed.

I don't remember if that was a default setting or if I added it in.  Do
I need that line to be there?

I noticed that without it, yum will perform an update on
kernel-hugemem-devel and kernel-smp-devel.  Is this a problem?

Thanks,

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.
