Yes, my milage varies. The gnu find I have is crossing boundries,
with or without out the -noleaf. But the -noleaf does not say
to not cross volume boundries, it says don't try to optimise the 
searching for directories, based on the hard link count.   

In the case where the -type d is used, we are still looking at all 
directories, and the mount point appears as a directory.
