There is a space for custom scripts, in the spec generation process.  It
is clear that you already have some custom script to help automate
building packages for all the different distro versions.  Just modify
the script to look for one of the things that Bill mentioned, and either
internally add 9 to the version or do something else to cause rpmvercmp
to sort your EVR before the older EVR.  No one is suggesting that
rpm/yum/up2date/anaconda/apt/red-carpet should be modified in any way.

Thanks.
