From e36066dcc3b56cac1c695370ea178b566c0ebfd6 Mon Sep 17 00:00:00 2001 From: Joshua Lock Date: Tue, 15 Nov 2016 22:08:54 +0000 Subject: lib/oe/lsb: better handle missing fields Some rolling release distros, such as Arch Linux, don't include a VERSION_ID field in their os-release file. Change release_dict_osr() to better handle this optional field being absent. Further improve the resilience of the release_dict_*() methods by always returning a dict and using dict.get() in distro_identifier() to supply a default, empty string, value when then key is missing.
