In commit 8689e561 (lib/oe/lsb: attempt to ensure consistent distro id regardless of source), the distro ID returned by oe.lsb.distro_identifier() was lowercased, but only if a release version is also present. This changes the code to always lowercase the distro ID, including the default distro ID "unknown", which is used if no other ID can be identified.
