# EXTRA PACKAGES
# --------------
# UcSlugC builds an openslug-image with no extra packages - to add packages to the
# firmware copy this file (to make a new 'distro' configuration file) and change
# the definition below to include the requirements.
# NOTE: as built this system will *not* be able to boot off anything other than
# the flash file system ('turnup' will not work).  You need to add the filesystem
# modules for your chosen root file system (and any others which will be used).
# See openslug.conf for a more full-featured system!
