I just used it (for the first time) to build the i386 and x86_64 DVDs. Each builds, one at a time. I used the original F7 ISOs as a starting point, mounted them on my system, and ran jigdo, selected the i386 ISO, pointed it at my mounted i386 DVD, and let it run. It took about 2 hours to download the 560 some changed RPMs, and created a new ISO image for me. *THEN* I was able to select the x86_64 DVD, and do the same thing for the almost 800 RPMs. I let this one run and some 3 hours later, I burned it as well. (Was there some overlap of the changed RPMs between the 2? probably, its not perfect, and doesn't remember what was already downloaded for a previous disk. Could it have? Maybe, I'm not sure, I haven't used it enough to proclaim myself an expert in it.) What I *did* find lacking was the documentation. It was written by people who had been using it probably for some time, and while it did a good job of telling you what dependencies you needed installed, it did a lousy job of showing you examples of running it. I guess its par for the course today where everyone who writes new programs just assumes you'll just jump in and run it and figure it all out on your own. But, that's my experience with it. Would a torrent have done just as well? Maybe, but it would've downloaded the entire 2.9 and 3.4 GB ISO images for both, not just the changed RPMs. Did I build any of the other 14 or so options? No, but interestingly enough, 5 CD sets were some of the choices, as were the SRPMS. I didn't want them, I didn't have to download them. The .jigdo file isn't much more than a structured text file listing the RPM contents of each disk. Comparing this list to a local repo structure allows it to figure out what's changed and only download those changed RPMs and rebuilds the ISO, then verifies the result against a known good checksum. > There is still no link on the Unity site to > http://fedora.kanarip.com/torrents/ just to the official Fedora > torrents. > > Anyone know if a torrent is available for this re-spin? Given how jigdo works, I don't think they plan on ever providing one. If all their server has to do is serve up the much smaller .jigdo file, and then put the entire download load on the updates mirrors. You are free to edit your .jigdo files to specify whatever mirrors you wish to choose to, or use the default list they provide. My experience is that the default servers weren't as fast as some of the ones tried for the "missing" RPMs after the first pass. But I had no way of knowing that up front. Of course, YMMV -- Kevin J.
