cuDNN installation document issue and .so file permission

In the installing guide https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html#installlinux-tar

$ sudo cp cuda/include/cudnn.h /usr/local/cuda/include
$ sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*

I think it should use cp -d to copy the library file since there are symbolic link in it.

Also, the libcudnn.so.7.5.0 file have execution permission (after untar). Though I don’t think it will cause any issue, it shouldn’t have the execution permission, right? All the other .so files didn’t have it.

I’m not sure if I post in the right place. Is these kind of topics should be here?
