Yes we do - if the client uses the UNIX extensions to
readlink. The problem is a UNIX extension client could
set a symlink on the server (which in a UNIX <--> UNIX
scenario would never be resolved on the server, but read
and resolved on the clients filesystem) and then do a
normal SMB open call on it to escape the restrictions
of exporting only a small part of the servers filesystem.

It can. I just can't trust the client to do this.
