For example, you can see both softhsm packages from the above builds in: http://mirror.centos.org/centos-8/8/AppStream/x86_64/os/Packages/ But the "modules" file currently pointed to by repomd.xml only contains metadata for build 265 (search for "stream: DL1"): http://mirror.centos.org/centos-8/8/AppStream/x86_64/os/repodata/15776f65b6612ee4b6acbc9f7b9981e88198a0b97b01a4ce98d7b0ab7ed28ccc-modules.yaml.gz I don't think there's any other way for dnf to tell that an RPM is part of a module before downloading it, but currently each time a module build is published it appears to push the previous version out of the "modules" repository metadata. This leads to the current behaviour where disabling a module only hides RPMs from the latest module build, and earlier versions "leak out" into transactions, eg: $ sudo dnf -y module disable go-toolset ... $ sudo dnf install golang (incorrectly offers to install package from previous module build)
