Do the old ones need to be kept around for GPL and other compliance? How does one get the source code of what XYZ image is and XYZ+1 image? This is where the disk storage becomes problematic and the mirroring harder. A lot of mirrors have a throughput of 1-5 Mb/s when combined with all the other people trying to mirror. Rawhide already overwhelms a bunch of them. We need to make sure that our 'update' path makes sense so that we meet a bunch of different things and make sure that people can actually sync. -- Stephen J Smoogen. _______________________________________________ infrastructure mailing list infrastructure@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/infrastructure@xxxxxxxxxxxxxxxxxxxxxxx
