Issue
What happens at rpm -U .. if any file of the package being updated has been modified? Is it left updated with a new one, or the new (modified) file is kept with new extension?
Solution
RPM will overwrite any files that have changed unless they are explicitly designated as "configuration" files using the %config flag. Then it will make a copy of either the new one (*.rpmnew) or the old one (*.rpmsave) based on whether or not the config file is flagged as noreplace. See this reference for more details.
