On a self-compiled system.

Forgot to enable namespaces in the kernel. Now it seems to work
as root, but not as an unprivileged user:


daemon@...habox:~ unshare -r -U
unshare: can't open '/proc/self/setgroups': Permission denied
daemon@...habox:~ unshare -f -r -U
unshare: can't open '/proc/self/setgroups': Permission denied
