vboxsf could not support symbolic link

[greegree]

1.Host is Mac OS Mavericks 10.9.2
2.VirtualBox is 4.3.12 r93733
3.Guest is ubuntu 12.04.03 LTS

mount a HFS+ as /media/sf_code
----mount
...
code on /media/sf_code type vboxsf (git=999,rw)
...

at /media/sf_code do this test:

"echo "test" > t.sh" ok
"cat t.sh" is echo "test"
"ln -s t.sh t1.sh" occur an error "ln: failed to create symbolic link 't2.sh' : Read-only file system

but at 4.3.12's release note ,it said the symbolic link is both ok.

why ?
