[CentOS] Is installonly option needed?

[Bowie Bailey]

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,
