+You will need to checkout the /puppet/modules directory.
+
+Then look at /puppet/manifests/nodes.pp (and the other .pp files from
+that directory) and use it as an example to create your own puppet files
+which include only the modules you want.
+
+Then fix some bugs, because there will probably be problems, as I don't
+know if someone already tried this yet.
+
+So it requires to know puppet, and the build system, and spend some time
+to make it work.
+
+So this is not easy. I think it could be nice later to be able to
+provide something to install a buildsystem easily. But it's not yet done.
+And probably not what you want if you only want to rebuild some
+packages in a chroot, iurt is enough for this.
