Hello everyone,
Thank you, Adrian, for mentioning it. I'm the CERN engineer responsible for that migration. As of today, we should be covered by Trixie (LTS + ELTS). However, we would like to have the possibility of upgrading to Forky. Having Forky support x86_64-v1 would give us a more modern system and a larger margin to both replace our x86_64-v1 hardware and cover the accelerator RUN (when beams will actually run).
