Way be when I first looked at downloading Debian, I had a similar

download and install a special program that I'm going to only use once

ftp, http, etc., why do I need to mess with this new program?
Well... it does use http. The why would be for similar reasons people
use torrent. Also like why you could use a telnet client to browse to
view a web page via http, but you get a browser instead (bad example).
Exactly my point.  I already have a bunch of programs to download
files.  "Bob" is going to ask why he can't just use IE, Firefox,
uTorrent, <insert P2P app-o-the-week>.  Why do I need this "special"
download program that I've never heard of that I will only use to
download Fedora?  If Linux is that hard, why bother...

Personally, I can see where jigdo makes sense if you already have some
of the files downloaded, but the new user is going to be starting from

Luckily, Jigdo isn't mutually exclusive with BitTorrent. Concerning the
issues stated, I hope distribution via BitTorrent is going to continue.
Jigdo is one way for users to get the distribution whereof I assume it
is a better and way more efficient way - for those who can use it.

Kind regards,

Frankly Bittorent+Jigdo seem the ideal combo. There is no one who
can't technically used jigdo, while there are who can't use torrent.

As a user who technically can not use torrent, I would like to know (and don't have time to understand the new tool yet), can I us jigdo with only a copy of a yum repo, i.e., if I do not have an ISO to diff against? Otherwise at least a "seed" ISO is going to be needed in the mirrors for each release.

And I assume that the md5/shasums of the resulting ISO will[1] NOT match those as produced by the fedora system in either case, correct? Which means I have to have rpm (armed with appropriate keys) walk the whole repository and verify packages before making the jigdo ISO.
