Oh, indeed.. Any suggestions? My other thought on this, is to add a tagging mechanism, that users can simply add tags to a generation, of which one could be the commit id. I think that having the upstream git commit ID already improves the situation. Adding external repositories is not something the upstream distribution can take care of. Maybe if we would add a different, more formal way of allowing external repositories, that could be dealt with more easily. (Is this what 'channels' could do?) Kind regards, Roel Janssen
