I can answer that, as I am one of the people behind the Debian packages. Yes, we do build in clean chroots. We use special tools for that that helps us a lot like cowbuilder, pbuilder or sbuild. If I need to "play" with the source (for example, for tracing a bug) I use schroot's capabilities to create "disposable" chroots. It takes some time to create them, but then I'm sure I'm in a clean environment with just the tools I need. This is specially true for libraries. For applications the packaging might start in a clean environment, but must end in a clean one before uploading. -- Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/
