--- Comment #5 from Jesse Allen the3dfxdude@gmail.com 2007-08-11 14:51:18 --- I would not think so, as the auto detection from /etc/fstab is not always what the user wants. Wine also automatically sets up drive letters from HAL too, so that is already taken care of too. I find what wineprefixcreate does is pretty reasonable.
Maybe wine can set up a drive letter for the home directory in wineprefixcreate? But most people install to drive C anyway so it doesn't matter. I don't think there are any pressing concerns here.
