Ok, you mean before creating the X.debian.tar.xz? Because before running pdebuild, uscan was used to provide the X.orig.tar.xz and in the folder where I run pdebuild there is only the debian/* files (without any extra file). I was thinking that pdebuild is somehow a way to build packages from a "read-only" (source) folder, ie. nothing to touch or clean before going! Thanks!
