It was used, at least for a while, on some Fedora spins and IIRC one or two fedora releases. If you are maintaining a personal/local mirror, jigdo makes regenerating 'official' media very fast. And with fedora if you were mirroring the development repo before release, then jigdo meant you could quickly have the 'official' media almost before a torrent could get it to you especially on a slow link (yes I know we don't do those kind of partial pre-releases in CentOS world). With CentOS they would be nice for those of us who mirror the whole tree and need media, so we could only download the OS directory effectively one time instead of 3 times (os dir, cd media iso, DVD media iso) and then jigdo to generate the iso's as needed. Oh, and you also don't have fun with broken proxies truncating DVDs that are 4GB like happened with CentOS 5.5. Added bonus... unlike bittorent, no ISPs block or mess with jigdo's traffic. Granted, I don't know how much of the community would make use of them and they take some cpu+labor time to generate. -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter
