Certainly something that looks worth looking into.
That would be quite nice, no one else has dynamic .metalinks on a large scale. When I got the F7 ISO, I noticed it would fit in well w/ the download pages which tell which mirrors have which releases. I think it would make things less frustrating for end users trying to get things, and hopefully create less strain on mirrors. Certain metalink clients will download from domestic mirrors first, if country info is in there, which should hopefully be more efficient for everyone. What can we do to make this happen? Is this the type of thing that's easier for the maintainer of MirrorManager to add, or should we supply a patch? Here's the current tools people have done, if that helps - http://www.metalinker.org/implementation.html#generate Metalink Editor - in Python, GUI cURL - they use a short Perl script that makes them based on location. Simba/RoPkg::Metalink - Perl Bouncer - there's a patch for it. Metalink tools - CLI, C++ Thanks too, Rahul. Would it be worth posting on infrastructure to see if people are interested now? -- (( Anthony Bryan )) Metalink [ http://www.metalinker.org ] -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
