+=== Note: ===
+There is a bug in createrepo that causes it to rewrite all the files incorrectly in primary.xml
+There is a string replace that is unended, replaces all occurences of _reldir with '', which replaces 1 and 2 with nothing
+
+relpath = self.localpath.replace(self._reldir, '')
+change the line to this:
+relpath = self.localpath.replace(self._reldir, '',1)
