I created testing repo [1] with two updated core modules and updates repo with perl(core) packages. I've tested this scenario: 1/ perl package with perl-Module-Build-0.3500-110.fc13 and perl-version-0.77-110.fc13 2/ update from [1] to perl-Module-Build-0.3603-1.perltestrepo.noarch.rpm and perl-version-0.79-1.perltestrepo.i686.rpm 3/ enable 'marcaperl-update.repo' 4/ update to perl-5.10.1-112.1.perltestrepo.i386.rpm, perl-version-0.80-112.1.perltestrepo.i386.rpm, perl-Module-Build-0.3500-112.1.perltestrepo.i386.rpm This should test whether yum can handle lower version in main and higher in separated package (Module::Build). The update of packages went fine if 'Obsoletes' is used in new package [2]. My proposal of updates shouldn't be included in packaging guidelines, so we should be able to change it flexibly to the current situation. Not sure if this change of packaging core modules must be discussed by FESCO because it's not mentioned in Packaging:Perl, but it could be viewed as conflict with common PackagingGuidelines. Also the time is not good with further disscusion on other channels, so please check/test, whether I missed something.
