{__python2} for el6?

Back in August, the {__python} macro was deprecated in favor of {__python2}. This is cool as it paves the way for an eventual python3 takeover. https://fedoraproject.org/w/index.php?title=Packaging:Python&diff=350... However, {__python} is still the expected macro for el6 builds. Many of us maintain single spec files that we build for Fedora and EPEL. - Does anyone have any recommendations about how to handle this? I recently started using this blurb at the top of my new spec files. Will it do? %if 0%{?rhel} && 0%{?rhel} <= 6 %{!?__python2: %global __python2 %{__python}} %{!?python2_sitelib: %global python2_sitelib %(%{__python} -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())")} %{!?python2_sitearch: %global python2_sitearch %(%{__python} -c "from distutils.sysconfig import get_python_lib; print(get_python_lib(1))")} %endif - If we decide on a canonical approach, can it be added to the Python guidelines as a recommendation?
