I think this is a good idea. We could have the kernel determine the
real uid of the process that's initiating the mount and have the upcall
use that instead of the uid= passed in via the mount options. Or...we
could have the mount helper determine this and pass in a "creduid" in
the mount options.

The only thing that makes me hesitate is that we probably have existing
users who are dependent on the current behavior. If we can come up with
a way to transition them smoothly, then I'm all for making this change.
