Hi Devs.
I've noticed recently that zsync fails to sync the Ubuntu Karmic final
iso from the releases.ubuntu.com server.
I was able to sync the beta and RC isos from this server without problems.

################---- 83.5%
zsync received a redirect/further action required status code: 302
zsync specifically refuses to proceed when a server requests further
action. This is because zsync makes a very large number of requests
per file retrieved, and so if zsync has to perform additional actions
per request, it further increases the load on the target server. The
person/entity who created this zsync file should change it to point
directly to a URL where the target file can be retrieved without
additional actions/redirects needing to be followed.
See http://zsync.moria.orc.uk/server-issues

Aborting, download available in ubuntu-9.10-desktop-i386.iso.part

I had to use one of the links to the Ubuntu mirrors to make it work.
I've found some quick links and a howto here:
http://ubuntu-tutorials.com/2009/10/29/use-zsync-to-update-existing-iso-images/

Can someone fix it? Or at least add some links of explanation at the
zsync downloads page?
Cheers,
