2009/387 [Pathname Reparse Points]

[Darren J Moffat]

This looks very cool but I haven't quite got my head around it 
completely yet.

What happens if open(2) is called with O_NOFOLLOW set on one of these 
reparse points ? (Please answer for ZFS local access, NFS and CIFS).

So why not just a system attribute to store the whole thing ? 
Particularly since it is required to store a system attribute to 
distinguish a reparse point from a normal symlink anyway.

Also if we do end up adding BSD magic link support for the link types 
they have can a symlink link still have reparse data in it ?
