Subject: [PATCH] 00251: Change user install location
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Change the values of sysconfig's "posix_prefix" install scheme to /usr/local
when RPM build or venv/virtualenv is not detected,
to make pip, sysconfig and distutils install into an isolated location.
The original values are saved as an additional "rpm_prefix" install scheme.
The site module adds the /usr/local paths to sys.path when site packages are
enabled and RPM build is not detected.
Fedora Change: https://fedoraproject.org/wiki/Changes/Making_sudo_pip_safe
Rewrote in Fedora 36+ to patch sysconfig instead of distutils,
see https://discuss.python.org/t/pep-632-deprecate-distutils-module/5134/104
Downstream only for now, waiting for https://bugs.python.org/issue43976
