      What were you trying to do that didn't work?

      Running `mock -r rhel-8-x86_64` (or derivates, such as `rhel+epel-8-x86_64`) on Fedora 40 fails with:

      This is due to https://fedoraproject.org/wiki/Changes/DNFConditionalFilelists

      mock uses bootstrap chroots to avoid such problems, but when constructing the bootstrap chroot itself, it already hits it: python3-dnf has a path-based dependency that dnf on f40+ cannot understand.

      A solution is to add manual `Provides: /usr/libexec/platform-python` to platform-python.

      Please provide the package NVR for which bug is seen: 3.6.8-62.el8_10

      How reproducible: always

      Steps to reproduce

      1. On Fedora 40 or newer
      2. Insatll mock
      3. (if you ever run mock before the system was updated to F40) mock -r rhel+epel-8-x86_64 --scurb=all
      4. mock -r rhel+epel-8-x86_64 --bootstrap-chroot --no-bootstrap-image init

      Expected results

      ...
      Finish: run

      Actual results

      ... nothing provides /usr/libexec/platform-python needed by python3-dnf-...
