- Remove custom COREOS_* attributes from /etc/lsb-release - Move dev image logic to dev_image_util For extra fun fix detection of local host URL for devserver. - Remove weirdly verbose "DESCRIPTION" format. - Add COREOS_RELEASE_BOARD back to /usr/share/coreos/release This is mostly just so update_engine and gmerge report the correct board name to devserver, informative-only on prod images. - Remove version info from /etc/gentoo-release - Switch from 'track' to 'group' terminology.
