As Michael Mol already said, tmpfs for the run dir is not a bad thing, it, it does not eat all your ram :) I however have a different question: Why do we need a new /run when we already have /var/run. There's no mention of /run in the FHS either. I only see udev stuff under /run - So it's another crazy udev thing? :)
