# IMAGE_FEATURES control content of the core reference images
# 
# By default we install packagegroup-core-boot and packagegroup-base-extended packages;
# this gives us working (console only) rootfs.
#
# Available IMAGE_FEATURES:
#
# - 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
# - tools-testapps      - tools usable to make some device tests
# - tools-sdk           - SDK (C/C++ compiler, autotools, etc.)
# - nfs-server          - NFS server
# - ssh-server-dropbear - SSH server (dropbear)
# - ssh-server-openssh  - SSH server (openssh)
# - qt4-pkgs            - Qt4/X11 and demo applications
# - hwcodecs            - Install hardware acceleration codecs
# - package-management  - installs package management tools and preserves the package manager database
# - debug-tweaks        - makes an image suitable for development, e.g. allowing passwordless root logins
# - 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
# - doc-pkgs            - documentation packages for all installed packages in the rootfs
# - ptest-pkgs          - ptest packages for all ptest-enabled recipes
# - read-only-rootfs    - tweaks an image to support read-only rootfs
