Because we can (will, actually) have nested fs root's for containers. IOW,
container's root will be accessible from it's creator context. And I want to
tune container's fs from creators context.

This is not so important for me, where to access sysctl's. But I'm worrying
about backward compatibility. IOW, I'm afraid of changing path
"/proc/sys/sunprc/*" to "/proc/<pid>/sys/sunrpc". This would break a lot of
user-space programs.
