I sometimes wonder if it&#x27;s possible to use a gobo-linux style system, whereby the package manager just downloads the package to a versioned folder, possibly expanding it out, to a a package cache - then the venv need only <i>symlink</i> to it. The same could be done for python installs. Then do the same for the system python (e.g &#x2F;bin&#x2F;python points to &#x2F;someplace&#x2F;pyjunk&#x2F;system&#x2F;python, which in turn is a symlink to a particular interpreter, e.g. &#x2F;someplace&#x2F;pyjunk&#x2F;interpreters&#x2F;py2&#x2F;2.7&#x2F;cython_2.7_blub-i386&#x2F;python).
