Michał, How does this work for fetch restricted files and finding other files no longer on the mirrors? Its no longer a download and move it to $DISTFILES, or is it? Whatever it is, users will need to do it unless files in $DISTFILES are accepted by package managers if they are not found in the main structure. -- Regards, Roy Bamford (Neddyseagoon) a member of elections gentoo-ops forum-mods
