I never worked on such a transition, so the entire set of implication isn't clear to me. I'm trying to understand how different behaviors in setting packaged relationships would impact user experience, could you please help me to make my mind clearer? First thing, the new ghc package conflicts and replaces with ghc6, so we're sure that no two different version of the same Haskell library will be installed at the same time: if they were, they would require ghc and ghc6 to be installed at the same time, contradiction. Now, we have to decide whether libghc6-*-* are automatically upgraded to the corresponding libghc-*-* for ghc version 7, aren't we? If we wanted to have the automatic upgrade, then introducing a dummy package which depends on the new package should be enough. Otherwise, we just don't add the dummy package. Am I correct? What would change if we added a Conflicts: from the new package to the old one?
