No, its a real thing just like a login. Does the kernel have any concept of a
login? Yet it happens. And it causes us to generate events describing who,
where from, role, success, and time of day. :-)

I don't doubt that just as user space sequences the actions that are a login.
I just need the kernel to do some book keeping and associate the necessary
attributes in the event record to be able to reconstruct what is actually
happening.
