That's true for sysfs.  The selinuxfs is a different beast and can make its
own choices.   The biggest gotcha is that you need to remain backwards-combatabl;e,
so anything that's there *now* has to remain there for a rather extensive
deprecation period.  Keep in mind that Andrew Morton just this week had an
issue with /proc/net that turned out to be because he had an FC5 policy loaded,
and that ancient policy didn't know that /proc/net is now a symlink...

What info would *ideally* be available for userspace?  Let's figure that out
first, and work backwards from there...
