[Bug 301289] [NEW] No support for zsync at Ubuntu ISOs

[psl]

Public bug reported:

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-8.04.1-dvd-amd64.iso
ubuntu-8.04.1-dvd-amd64.iso.torrent
ubuntu-8.04.1-dvd-amd64.iso.jidgo

Ubuntu should generate zsync files too, like:
ubuntu-8.04.1-dvd-amd64.iso.zsync

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.
