Yes, I think that would make sense. > I do not have a wording right now for dev-ref, but I can look if I can > come up with something during the weekend (keep in mind though that it > will in any case need review, I'm not a native english speaker). Great! I'm not a native speaker either, but I'll happy to look at it. Maybe cc debian-release@ with the patch so the SRMs can look at it as well. Cheers, Emilio
