Bug Description
Binary package hint: zsync
This is not a real bug but I don't know where to enter this improvement.
ISO images of Ubuntu are distributed in many ways. RAW ISO, Jidgo support, etc. I miss support for zsync.
zsync is similar to rsync but is designed for client download, it doesn't create no extra load on the server, and no rsync is required to run on the server. zsync uses standard HTTP protocol and only needs a special file with metadata at web server, file that has pre-calculated checksums for rsync algorithm.
This ticket is about request to add files with zsync extension for every Ubuntu ISO you have. It will enable download of Ubuntu ISO images from web servers in efficient way with zsync client when user has older ISO image.
Ubuntu current generates support files for torrent and jidgo as I know.
Example:
ubuntu-
ubuntu-
ubuntu-
Ubuntu should generate zsync files too, like:
ubuntu-
Information about pre-calculated checksums for the rsync algorithm stored in "zsync file", this file is downloaded by zsync client first and is used to download iso file in efficient way, like rsync does. File with zsync meta data is creted with "zsyncmake" utility.

This is way I think that zsync files can be created:
for FILE in *.iso; do
echo "Processing "$FILE"
zsyncmake -v -u "$FILE" -f "$FILE" -o "${FILE}.zsync" "$FILE"
done
