2.2.2. Jigdo

Fedora releases are also available via Jigdo. This distribution method can improve the speed of obtaining the installation ISO images. Instead of waiting for torrent downloads to complete, Jigdo seeks the fastest mirrors it can find via the Fedora Project Mirror Manager infrastructure, and downloads the bits it needs from these mirrors. To optimize seeking these bits, you can tell Jigdo to scan a DVD or CD you already have, and cut down on redundant downloads. This feature becomes particularly useful if you:
  1. Download all the test releases and then get the final release, in which case you have 90% of the data already with each subsequent download.
  2. Download both the DVD and the CD set, in which case the DVD holds 95% of the data needed for the CD sets.
  3. Download any combination of the above.
