>
> ViewFileSystem doesn't override FileSystem#getLinkTarget(). So, when view
> filesystem is used to resolve the symbolic links, the default FileSystem
> implementation throws UnsupportedOperationException.
> The proposal is to define getLinkTarget() for ViewFileSystem and invoke the
> target FileSystem for resolving the symbolic links. Path thus returned is
> preferred to be a viewfs qualified path, so that it can be used again on the
> ViewFileSystem handle.
