Comment 28 for bug 657564

I don't see a reason not to use the debian package as a basis.

 - the -integration package from plug-ins could be added as a delta in the
   ubuntu package. You could add similar dependency packages for other
   use cases.

 - If a dependency is not absolutely required, then make them a recommendation
   or a suggestion.

That leaves the case, where ubuntu is a version ahead of debian, and the burden of maintaining the separately packaged plugins is left to the ubuntu uploader.

So please make up a choice, maybe bring it to the technical board, or else I'll roll the dice and remove one package before the oneiric release ;)
