I always get an operation not permitted error.

My understand is that CLONE_NEWUSER should not require any special capabilities. I tried the sample code from the manpage and also from LWN.net, but both give me the same error. It works for me on 3.16 and 3.15 but not on 3.15.8-200.fc20.x86_64. I'm a bit confused.
