[mirror-admin] fedora live images dos attack?

[Mirrors]

Well,

>From what I know of jigdo, it downloads all the seperate files, and 
basicly uses a jigdo template to assemble the ISO locally.

I had to configure it on my mirror server to download deban isos a long 
time ago.

The concept is supposed to be that if only 50% of the ISO is new content 
then you only download the packages that changed, and then re-make a new 
current ISO.
