Well there's a workaround called "Minshall/French" symlink format:
that hides the symlink target inside a 'special' file. That
should still work over SMB2, but it's tunnelling stuff inside
the protocol, not really protocol support.
It's what the Linux CIFS client uses when it has to do
symlinks against a Windows server which doesnt' support
the UNIX extensions.
