We'll need this mapping anyway, in this case the best way I think is to script this drive removal unless it affects more installers.
Is there anything in Wine that requires this mapping? I thought files outside of drive mappings could still be accessed through ??\unix paths. It certainly is convenient to have that mapping because you don't need to use 'wine start /unix ...' for example, but perhaps we could be smarter about that?
I'm not saying we shouldn't map root by default, I'm just pointing out that on Windows you're much more unlikely to hit this case.
