Hi David,
I checked with Olaf Kirch on this a while back, and he seemed to think
it would be better not to change the behavior. It's apparently tricky
from a security standpoint to keep each mount within its own sandbox if
you allow multiple directories from one fs to be exported. (I haven't
looked into it that closely yet.)

So for now just export the parent directory and use the permissions to
limit access.

Regards,
Bill
