Thanks for your report. Your idea would be better off being registered as a specification as it's a request that would probably require things changing at lots of places.
You should first check whether it already exists at the Ubuntu specs page (https://launchpad.net/distros/ubuntu/+specs) in Launchpad. If that is the case, feel free to contact the drafter of that spec about your comments/suggestions. Otherwise you can start writing a spec following the steps described in https://wiki.ubuntu.com/FeatureSpecifications. Thanks. ** Changed in: Ubuntu Status: Unconfirmed => Rejected -- *ubuntu should use deltaiso-s during development https://launchpad.net/bugs/60107 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
