Can we see the code first ? Creating server-side symlinks
is a *VERY* dangerous thing to be doing, and we're moving
away from this.

The current plan is to represent "real" symlinks on the
server filesystem as reparse points, and for clients to
create reparse points the "correct" SMB way in order
to be represented as symlinks to a client.

We really would prefer not to allow any "real" server-side
symlinks to be created by clients, as these are ideal for
creating race-condition security holes.
