 Since userspace needs to see the @magic tokens (as we've seen), and realpath(3)
 seems to the cause of all this, I think we should just fix it to expand those
 tokens when magic-symlinks are active. That should take care of 1)--even though
 this means duplicating the expansion already being done in the kernel.
 
 Shouldn't be hard. I'll do it--but, prolly only next week.
 
 Thx,
