* Merge from debian unstable, remaining changes: - debian/patches/do-not-install-debfoster-into-chroots.patch: do not install debfoster into the chroots because it is in universe and not needed for package building itself. - debian/patches/run-pre-build-hooks-as-root.patch: run pre-build hooks as root (Closes: #607228) * Now that the package uses a patch system, don't modify the files directly; instead, put the changes in the respective patches and add the DEP-3 patch tagging guidelines to them.
