For some reasons, the development branch of the frontend I created performs a 'mount a /Volumes/', if I let it imgmount a hard disk image created with Virtual PC 2007 (*.vhd) to either c or d within DOSBox.
I've no idea why my development branch forces to do this, but I've taken a deeper look into it and must tell the following:

DOSBox Mt. Everything of type folder if it is located in the root of boot drive of Mac OS X, even invisible ones (like the folder 'Volumes' mentioned above, which holds aliases to all the drives mounted to the host OS).
I've no clue how to prevent DOSBox from doing so.

Because Mac OS X is unix based, maybe the same problem happens on other Unix or Linux based systems, too?

It is the same as if you open the 'Go' menu of the Finder and call the command 'Go to Folder', to enter '/etc', for example.
You can do a 'mount a /etc' inside DOSBox the same way, without entering the complete path to the folder, which is "/Volumes/Macintosh HD/etc/".
You can even do a 'mount a /system' which is the System folder Mac OS X booted of.

I don't know how important this case is, but is it problably a security hole?
