When you run dpkg-buildpackage, it also runs debian/rules clean prior to running dpkg-source -b to pack up the source package. sbuild is simply copying the behaviour of dpkg-buildpackage here. From what I understand, if we omit the clean, we would potentially pack up a dirty source tree. We don't build the source tree directly--it's a requirement that we pack it up prior to building. I think it's important to point out that sbuild itself /does not build source trees/. It builds Debian packages from a .dsc. I.e. from a Debian source package. If you run sbuild with a .dsc or package_version rather than a directory, it will do all its work inside the chroot. Part of the job of sbuild is doing clean builds of packages; you can't do a clean build starting from a dirty tree. When you run in a source tree, we support purely as a convenience and for dpkg-buildpackage compatibility, it will pack up the source into a .dsc prior to running normally as above. This can never be done inside the chroot, because you run sbuild outside. The working directory isn't guaranteed to be inside the chroot either, and in the medium term it's also incompatible with privelege separation inside and outside the chroot. We could potentially copy the entire unpacked tree into the chroot. But internally sbuild only deals with .dsc files; we need a .dsc to get the build-deps and the other metadata required for the build. While it would technically be possible to also obtain the information from debian/control, this would introduce multiple codepaths to do the same thing, and the new codepaths would be untested and would be used far less than the existing ones.
