[bug#64573] [PATCH 0/3] guix: build: python-build-system: Have applications by default ignore non-Guix libraries in user site dir

[Lars-Dominik Braun]

Hi,

if we’re patching applications like pip anyways, what stops us from
just setting site.ENABLE_USER_SITE to False globally in Python’s
site.py?

Note that our python package currently (unfortunately) bundles and
exposes pip (through the pip3 command), which would not be affected by
your change to the python-pip package. Also note that we have
*two* build systems for Python right now (python-build-system and
pyproject-build-system) and the new flag disable-user-site? would have
to be added to both, even though they share the wrap phase.

Cheers,
Lars
