debdelta

[jfernyhough]

So I installed Fedora 17 in a VM and noticed presto does a pretty good job of reducing the need for downloading updated rpms. Debian do something similar with pdiffs for package list updates, and there's debdelta-upgrade for downloading deb deltas.

Why does Ubuntu not have this yet?

There was some work done in 2011: https://wiki.ubuntu.com/UbuntuDebdeltaSupport but the linked UDS meeting page is 404: http://summit.ubuntu.com/uds-o/meeting/foundations-o-debdelta/

Could you please ask the moderators to move your post into the Community Cafe. This section is not the right place for topics like this.
