More precisely, you don't need Depends: foo:arch if we have a suitably scalable solution that can be implemented using Provides. I.e., versioned Provides support is only a barrier to adoption to the extent that we have packages providing plugin interfaces, for which we want to support multiarch consumers, and the plugin interfaces rev frequently. > I think packages with a versioned depends on a provided package will > be uninstallable with the current dpkg, right?

Having packages that can't be installed with previous-generation package management tools should be ok, it's only having packages that are installed when they shouldn't be that really becomes a problem. > Only the "dpkg:arch" is required and that can be done with "Provides: > dpkg-arch" again. Right. I wonder if even this should strictly be necessary, though, or if dpkg shouldn't be able to provide the needed features for build-essential in any architecture version... > So we don't have to change the syntax but we do have to change dpkg > to smooth the way ahead for etch+1. Yes. Cheers, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world. [EMAIL PROTECTED] http://www.debian.org/
