# By default we install packagegroup-core-boot and packagegroup-base-extended packages;
# this gives us working (console only) rootfs.
#
# Available IMAGE_FEATURES:
#
# - weston              - Weston Wayland compositor
# - x11                 - X server
# - x11-base            - X server with minimal environment
# - x11-sato            - OpenedHand Sato environment
# - tools-debug         - debugging tools
# - eclipse-debug       - Eclipse remote debugging support
# - tools-profile       - profiling tools

#   - empty-root-password
#   - allow-empty-password
#   - allow-root-login
#   - post-install-logging
# - serial-autologin-root - with 'empty-root-password': autologin 'root' on the serial console
# - dev-pkgs            - development packages (headers, etc.) for all installed packages in the rootfs
# - dbg-pkgs            - debug symbol packages for all installed packages in the rootfs
# - lic-pkgs            - license packages for all installed pacakges in the rootfs, requires
#                         LICENSE_CREATE_PACKAGE="1" to be set when building packages too
# - doc-pkgs            - documentation packages for all installed packages in the rootfs
# - bash-completion-pkgs - bash-completion packages for recipes using bash-completion bbclass
# - ptest-pkgs          - ptest packages for all ptest-enabled recipes
