Hello, from documentation: https://docs.python.org/3/library/venv.html "python3 -m venv /path/to/new/virtual/environment Running this command creates the target directory (creating any parent directories that don’t exist already) and places a pyvenv.cfg file in it with a home key pointing to the Python installation from which the command was run. It also creates a bin (or Scripts on Windows) subdirectory containing **a copy** of the python binary (or binaries, in the case of Windows)." This is not true. In my case it creates symlinks to python binary by default. This is quite different. Upgrading system's python version broke my virtual environment because I believed I'm having a static copy of python binary in my virtual environment.

Correct, that should say something like "copy/symlink of the Python binary/binaries (as appropriate by the platform or arguments used at environment creation time)."

Obviously if you're willing to create a PR, Marcin, that would be great!

Actually the documentation hasn't been regenerated yet. I hope it will over night?
