I am using 'daisy' branch and minimal-image with the following (no X11)

IMAGE_INSTALL_append += "gcc g++ binutils libgcc libgcc-dev libstdc++

alsa-tools alsa-state alsa-utils-alsaconf \
tslib evtest dbus nano qtbase qtbase-fonts qtbase-plugins 
qtbase-examples cinematicexperience gstreamer \
cairo pango fontconfig freetype pulseaudio"
DISTRO_FEATURES_remove = "x11 wayland"
