 i'll have a look tomorrow, I'd guess that the relevant NDINIT(), or
 a later assignment to cn_flags, isn't setting TRYEMULROOT.
 
 Since namei() is handling the emulation root lookup, ktrace() will
 only show the application suppied path, I might look at a way of
 indicating that the emulation root might be (or way) used.
