From 2ddd6ddaf0c5ba14ae83347eba877ac9ef179c76 Mon Sep 17 00:00:00 2001 From: Joshua Lock Date: Tue, 8 Nov 2016 14:49:54 +0000 Subject: lib/oe/lsb: make the release dict keys consistent regardless of source Rather than have the distro_identifier method look for different keys in the dict depending on the source ensure that each function for retrieving release data uses the same key names in the returned dict.
