比较

   rpm {-U|--upgrade} [install-options] PACKAGE_FILE ...

   This  upgrades  or  installs the package currently installed to a newer
   version.  This is the same as install, except all other  version(s)  of
   the package are removed after the new package is installed.

到

   rpm {-F|--freshen} [install-options] PACKAGE_FILE ...

   This  will upgrade packages, but only ones for which an earlier version
   is installed.
