If apt-cross gets the calculation wrong and downloads debconf, dpkg-cross will create an empty debconf-armel-cross package. This all happens BEFORE dpkg-cross gets involved - it has to be decided by the tool doing the downloading. > >> But yes, worst case we end up pulling a -arch-cross package in that is > >> just empty.

No, that is not a sufficient measure of "useful" for dpkg-cross. dpkg-cross needs to see the files in order to say if there are any useful ones. > It does not tell you wether the dependency chain > ends there or crosses into the native chain.

The whole point of this Policy change is that Arch:all packages WILL need to be converted, we just won't know which we can allow and which we cannot. -- Neil Williams ============= http://www.data-freedom.org/ http://www.linux.codehelp.co.uk/ http://e-mail.is-not-s.ms/
