# CMDLINE* macros define the kernel command line. CMDLINE_DEBUG is provided

# appended to the openslug-image build by classes/nslu2-jffs2-image.bbclass
# (note that you can, instead, simply add 'inherit nslu2-jffs2-image' to
# openslug-image.bb). If you do this you will need to find a source for the
# LinkSys software to be placed in the full image - 'RedBoot' (the boot loader),
# 'Trailer' (just a bunch of bytes to flag the image as valid) and 'SysConf'
# (actually just a block of unset data - you could modify this to pre-configure
# the SysConf partition of the image). If you own an NSLU2 then this data is
# already in the flash of the NSLU2 and you can download it (including new
# versions) from the LinkSys web site - the bbclass will output information
# about where to put the downloaded data.
#
#NOTE: you do not actually need the boot loader in normal use because it is
# *not* overwritten by a standard upslug upgrade, so you can make an image with
# just non-LinkSys software which can be flashed into the NSLU2.

# 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!
