If I understood him correctly marcin seems to mount a windows share on linux 
via some vbox-proprietary pseudo filesystem. That wont get detected and thus 
no junctions will be used... (I have doubts you even can create them via 
vboxfs (or even smb)).
I would consider that a unsupported setup. Agreed?
