RPM names are always of the form Name-Version-Release, this is often abbreviated NVR. For Fedora/RHEL/CentOS systems the RPM name will always be suffixed with the “distribution tag” or disttag for short, this yields Name-Version-Release.disttag. Let’s look at an example: freeradius-2.1.1-7.fc10 The Name of this RPM is “freeradius”. The Version of this RPM is “2.1.1”. The Version always matches the upstream FreeRADIUS project version. In this example it means the RPM is based on the 2.1.1 version from the FreeRADIUS project. The Release of this RPM is “7”. This means the base version (e.g. 2.1.1) has been built 7 times each with something uniquely new to the base version. Sometimes this means a patch has been added to fix a bug, or it might mean a build option in the spec file changed, or the package was rebuilt with a new compiler. The reasons why the package was rebuilt with a new release number will be captured in the RPM changelog. The distribution or disttag of this RPM is “fc10”.
