[Bug 21837] Re: debdelta integration / zsync support

[Gabe Gorelick]

https://wiki.ubuntu.com/SmallerUpdates gives a lot of (outdated?)
information on this.

This problem is even more serious now that Ubuntu is pushing paid apps
like games through the Software Store. Downloading a 4 GB game for a
simple bug fix is not pleasant.

Title:
  debdelta integration / zsync support

Status in APT:
  Unknown
Status in “apt” package in Ubuntu:
  Confirmed
Status in “apt” package in Baltix:
  New

Bug description:
  Ubuntu should, like Mandrake 10.2, Firefox 1.5 and Windows, update packages
  using binary patches instead of by re-downloading entire packages. This would be
  especially helpful when running beta versions of software which change daily.
