Actually, zsync would be a better choice than rsync, since its efficiency should be identical in the same situations, but unlike rsync, it puts the CPU burden on the client instead of the server. Unfortunately, it's not available for Fedora yet (at least in the standard repos). So I guess the questions are, how long before zsync is available, and would the server be capable of running rsync until then? Another reason this would be useful is that the programs for creating and using deltaisos currently only allow one input ISO. I did some casual browsing of the source code, and from what I can tell fixing this isn't just a trivial matter of adding a loop. However, as long as one of the install disc sets consists of a single disc (such as the DVD ISO currently), deltaisos can be provided for just that (which I've been doing), and then rsync/zsync could be used to convert between the different disc sets for a given Fedora version. Even if the DVD set splits, there's still dual layer and Blu-ray, so for the foreseeable future there should still exist a single large install image. http://kparal.wordpress.com/2009/09/01/zsync-transfer-large-files-efficiently/ https://fedorahosted.org/fesco/ticket/134 https://bugzilla.redhat.com/show_bug.cgi?id=490140 -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
