- rename /etc/extlinux-conf to /etc/update-extlinux.conf - Do not exit with fail if update-extlinux.conf is missing - Always warn if root= is not defined in update-extlinux.conf - Try harder to detect the root device by parsing /proc/mounts - Exit with error if we cannot detect the Root device - Rename fancy_menu to vesa_menu - Unifiy the code generating vesa/standard menus - Keep a backup of old extlinux.conf - add "overwrite" config option so it is possible to skip overwriting the extlinux.conf. - Added a post-upgrade that imports current extlinux.conf to update-extlinux.conf
