It was very easy to setup because Hudson has a bzr plugin. It polls the repos and decides if a rebuild is needed, and shows diffs between builds and so on. My interest is more in seeing if different branches build from a clean checkout properly on different plattforms, not so much if a bootstrap is needed. Currently the setup is too insecure to let out on the internet, I need to chroot the build environment at least. -- Joakim Verona
