Over on python-dev we're talking about Linux Distributions switching from python2 to python3, what steps they need to take and in what order. One of the things that's come up [1]_ is that a very early step in the process is making sure that shebang lines use /usr/bin/python2 or /usr/bin/python3 as noted in PEP394 [2]_. Faced with the prospect of patching a whole bunch of scripts in the distribution, I'm wondering what distutils, distlib, setuptools, etc do with shebang lines. * Do they rewrite shebang lines? * If so, do they use #!/usr/bin/python2 or do they use #!/usr/bin/python ? * If the latter, is there hope that we could change that to match with PEP-394's recommendations? (setuptools seems to be moving relatively quickly these days so that seems reasonably easy.... distutils is tied to the release schedule of core python-2.7.x although if the change is accepted into the CPython tree we might consider backporting it to the current distribution package early.
