Awesome, I was wondering how to handle uid's from different namespaces cleanly in Coda's userspace daemon without resorting to exporting kuids to userspace. But this is a much more elegant solution, every namespace that cares about Coda should just run their own mountpoint and userspace daemon. Jan
