    Be more careful about ComponentId versus UnitId. · bd7e2310

    Two big ideas:
    
        * @--dependency@ takes a ComponentId, not UnitId.
          I used to think it should be a UnitId but it is
          now clear that you want to finger the indefinite
          unit id, which can be uniquely identified with
          a ComponentId
    
        * When hashing for an InstalledPackageId in
          new-build, we should produce a ComponentId,
          not a UnitId.
    
    While cleaning up the results, for any codepaths which we don't plan on
    implementing Backpack (Distribution.Client.Install, I'm looking at you),
    just coerce ComponentId into UnitIds as necessary.
