Although it would sure be nice if *all* updates to config files could be
counted on to not replace customized/local ones, this has not been
reliable at all. After each upgrade, I normally post about this as a
reminder. This time I thought "Everybody knows by now". Sheesh. So here
it is again.

Folks, be sure to do an updatedb and then locate rpmsave and rpmnew
after upgrading the system. Then you can make sure your local changes
get propagated into the updated system.
