I really need this feature, right now,some process such as
logind are broken in container becase we leak of this feature.

I notice this problem has been fixed in audit tree, so may be
I don't need to clean up loginuid when we create audit namespace.

And in audit tree, audit socket is per net namespace, hmm, I want
to know if anybody has a solution to allow processes to generate
USER_MSG type of audit message in un init pid/user namepsace.

Any idea? Eric,Steve,Richard?

Thanks
