Just a small change to a couple of scripts to go from #!/usr/bin/env python to #!/usr/bin/python This shouldn't effect anyone, unless they don't install python there. In preparation for python3, Fedora is doing a big push to change the scripts to use the system python. This allows developers to put the python3 in their path without fear of breaking existing scripts. Now I am pretty sure anyone using python3 for testing purposes will probably not run any of the scripts I changed, but Fedora has this automated tool that checks for this stuff so I thought I would try to push it upstream.
