Subject: [PATCH] Bootstrap remove venv for running ansible from

God pip is just the absolute goddamn worst holy shit
It took me like two hours to dig myself out of the compatibility problems
trying to install docker bindings to the system python gave me. This will
teach me to never install anything to the system python ever again. God I
hate pip
