+Subject: [PATCH] genconfig.py: update shebang
+
+It fails to call genconfig.py if no /usr/bin/python on build machine:
+
+| ./genconfig.py mcelog.conf config-intro.man > mcelog.conf.5
+| /bin/sh: ./genconfig.py: /usr/bin/python: bad interpreter: No such file or directory
+| Makefile:71: recipe for target 'mcelog.conf.5' failed
+
+Update shebang with 'env python3' instead.
+
+Upstream-Status: Pending
