I didn't know about this patch. There is also a bug on Ubuntu (54180), but it looks like nothing has moved. So let's hope we will have it someday. BTW, about compression, we just have gzip. Where is LZMA? It would be useful on slow links (e.g., all ADSL uplinks) :-) Maybe extra ciphers and compressions could be handled as plugins. -- Roberto Ragusa mail at robertoragusa.it -- 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
