Hi, since the discussion goes back and forth on this blog-post, I thought I throw in the actual answer of lennart poettering to it: https://plus.google.com/u/0/+LennartPoetteringTheOneAndOnly/posts/aSYnf3wNf8h And this is pretty much all of my contribution to it, it just annoyed me, that no one seemed to mention that there is an "official" answer to this. Best, Axel Wagner
