Yes it does in most cases, but --system-site-packages can do the wrong thing in certain edge-cases like trying to find a sane interface to libmagic in Python. There are at least three different Python modules available on PyPI that provide the magic module, i.e. "import magic", and *all* of them have *different* APIs. If you're lucky, you end up deploying on a distro (e.g. in shared hosting or in a PaaS like Openshift) that has the wrong magic module installed on the system, and your application/library crashes and burns in a very spectacular manner. -- Kind regards, Loong Jin
