Jigdo (portmanteau of "Jigsaw" and "download") is a download utility initially designed around the Debian distribution of GNU/Linux that downloads files from several mirrors in order to build an optical disk image. Jigdo is free software, released under the GNU General Public License. Currently Ubuntu,[2] Fedora,[3] Solaris,[citation needed] and FreeBSD[citation needed] are also available through Jigdo. A typical application of Jigdo is with its Jigdo was implemented in Debian in order to reduce the need to have many CD image mirror sites, locations with sufficient disk space and bandwidth to serve numerous 650 MB files (and in more recent times, 4.7 GB files for DVD images). Instead, Jigdo files allow mirrors to carry the regular Debian archive, where packages are not grouped together in image files and instead kept separately where they are also accessible through apt-get and still allow for the making of optical disk images. A second benefit is that if files on the CD image change, Jigdo only downloads the changed files and assembles a new CD image. In this way upgrading of CD images requires much less downloading.
[edit] FedoraSince the release of Fedora 9 Alpha,[3] all future release of Fedora will provide Jigdo as an alternative download method for people without BitTorrent access.[4] Also, Jigdo versions of Fedora 8 discs are available[5] as well as many other variants.[6] [edit] pyJigdoDue to the moribund state of the original Jigdo code—the GUI client does not support multi-image templates, meaning the command-line tools are required—Fedora has been developing a Python-based GUI, called pyJigdo.
