def vagrant_upload(args):
    """Replaces an input file in the VM.
    """
    target = Path(args.target[0])
    files = args.file
    unpacked_info = read_dict(target)
    input_files = unpacked_info.setdefault('input_files', {})
    use_chroot = unpacked_info['use_chroot']

    try:
        SSHUploader(target, input_files, files, use_chroot)
    finally:
        write_dict(target, unpacked_info)
