cuDNN installation document issue and .so file permission

In the installing guide

$ 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 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?
