It appears that none of you in this thread understands just how jigdo
really works.

1: The Fedora-Unity site only offers the new iso template and
configuration files to run this particular jigdo. They do *not* provide
any of the rpm packages.

2: You, *if* you have a set of CDs or a DVD, offer the packages that have
not been updated from them, and they are copied and placed into the new
iso template.

3: The packages that *have* been updated are downloaded using the same
mirrors that the regular Fedora updates come from and are placed into the
iso template.

4: When jigdo finishes you have a shiny new DVD iso or a set of CD isos
with unchanged packages, provided by you, and the changed packages
provided by the Fedora mirrors.

Not at all like bittorrent. More like rsync.

This system was not intended to download a whole DVD or set of CDs. It
makes updated media.

For me? A DVD takes, depends, one and one-half to 2 hours. CDs about
twenty minutes. Bittorrent takes forever.  ;-)
