+Subject: [PATCH] ufw: Fix dynamic update of python shebang
+
+[meta-openembedded ticket #327] -- https://github.com/openembedded/meta-openembedded/issues/327
+
+The python version in the shebang at the begining of the ufw script
+should be the same one as the version the setup.py script was called
+with.
+
+The fix in patch "setup-only-make-one-reference-to-env.patch"
+depends on sys.executable returning "/usr/bin/env pythonX". However,
+it returns "/usr/bin/pythonX". Using sys.version_info we can get the
+major version of the python used to called the script and append
+that to the shebang line so it works as intended.
