I've put up a set of rawhide DVD images.  If it had signed copies of
the packages it could be considered RC1, but since it doesn't, it
isn't.  However as many eyes on it as possible would be great.  We
don't get that many opportunities to test DVD install methods and such.

As always, images are available from http://torrent.fedoraproject.org
Too bad you can't tell torrent "hit this local torrent 'proxy/cache' and if it has a copy get my data (including others to connect from/to) from there".

Note: --tracker_proxy only connects you to an http proxy so you can make the initial connection, not the download||upload connections. there exists no torrent_proxy.

Yes it is sad to only be a leach, but if we could operate our download that way at all then we might be able to contribute in other ways.
I have a solution for this which is a python script with the name:
archive-teleconstructor.py
For the orginal message see:

Basically, it uses some info on the structure of an iso to insert bits of the iso that are already available locally {eg from an earlier test release, or a yum keepcache=1}. Depending on the sameness of the current iso to the previous downloaded material, you might save 50 - 80% of downloads or that 3GB iso.

The following list archive has the gory details - it is all command line stuff, and works with a bit torrent client that can analyze and verify it's own pre-downloaded parts. I have only used it with azureus.

Would someone who already has the complete download be able to run:
iso-info -q -l -i /home/old/8/rawhide-dvd-20071024-i386.iso >rawhide-dvd-20071024-i386.iso-info.txt ,
and then compress and attach that file to a reply to this email ?

The way to get the iso-info currently is for someone who already has the wanted iso to run iso-info on it. {its usually on 200kB - the ~ equivalent with jigdo is 200MB }

I would like to confirm that archive-teleconstructor.py still achieves the the bittorrent download saving. I was able to get F7 this way, downloading around 40% of the actual size. I left that torrent running for a month {outbound around 120GB or 40 copies of the dvd iso}. It is azureus's check feature that guarantees the bits are complete.

Questions, comments please email me.
