I think that I understand the principal behind this. Disk space nor bandwidth are not problems for me. I was thinking of others that might have a bandwidth/byte counter problem. Explain to me just how downloading only a part of the new ISO, the changes, and then creating the new one with parts of the old ISO and the new parts. How can that be the same as downloading the whole new ISO? Or am I not understanding how this works. -- David -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
