I have followed this discussion, since we provide an image based debian con nuestro producto, and we have realized that in part is right... the program gives options to alter all sources of packages except the "backports"... because you can alter all and not that?
I don't think that the excuse of "all are always in the same source" is valid, because according to the installation images as well as the backports images are not always coordinated between all the mirrors origins according to the debian notes.
In addition, not all the countries have excelent internet providers and the net service are expensive in some cases.. so please.. seems all of you must take care of the common environment not just only the Debian excelent resources environment with great bandwith
