No, it is very odd. It smells like a kernel issue to me. What version are you running ? I've also tried running the demo programs shown on the LWN.net article https://lwn.net/Articles/532593/ and they don't operate in the way described by the article - the demo programs continue to ru as 'nfsnobody' even after the mappings are setup. I'm just using the Fedora 3.9.4-303 kernel, rebuilt with userns enabled in KConfig. I'm wondering if there is still stuff missing in 3.9.x that prevents this from working properly, or if the kernel behaviour changed after those LWN articles were written.
