Woosh - that largely went over my head. It sounds rather complicated. Did I get the gist right: To paraphrase, if I declare a dependency on revision X, then what will be installed could be X or an EARLIER revision - stepping back until an installable revision is found. (Here I'd have called X a "maximum" revision, but this is seemingly open to two opposite view points - thus our confusion). That is very different to what I (and Bjorn?) had understood you to mean by "minimum", namely if we declare a dependency on revision X, then we'll get either X or a LATER revision. I guess this means an option to explicitly ask for the latest revision would be regarded as counter to the Galaxy reproducibility goals?
