Description

Currently ViewFileSystemOverloadScheme uses ViewFileSystem default behavior. ViewFS represents the mount links as symlinks always. Since ViewFSOverloadScheme, we can have any scheme, and that scheme fs does not have symlinks, ViewFs behavior symlinks can confuse.

So, here I propose to represent mount links as non symlinks in ViewFSOverloadScheme
