That is one annoying limitation of the shutil module, especially if the
destination is a mount point.

You could use copy_tree in distutils which is more like cp(1):
distutils.dir_util.copy_tree(srcpath, destpath, preserve_symlinks=True)
I have used this once outside of a setup.py and it works fine. This is
really more of a FWIW rather than insistence on not just running cp. I'm ok
with that, I just tend to think it's unnecessary.
