Comment 5 for bug 685571

If repeatable "debianized tree output" is one of the design goals of the build recipe concept then surely what we are asking for here is impossible? I'd still like to explore solutions, though, but first I have a question:

Can somebody elaborate on why repeatable source packages are so important and how running the code in a launchpad hosted sandbox is not sufficient?
