# IMAGE_PREPROCESS_COMMAND is run before making the image.
# We use this to do a few things:
# . remove the uImage, which is in a separate part of the flash already.
# . adjust the default run level (sysvinit is 5 by default, we like 3)
# . set a default root password, which is no more secure than a blank one
# (since it is documented, in case you were wondering)
# . make the boot more verbose

# CONFIG:
# SLUGOS_EXTRA_RDEPENDS: set in conf, things to add to the image
# SLUGOS_SUPPORT: set to here, see below, added to the image.
# SLUGOS_KERNEL: set here, kernel modules added to the image
#
# Do not override the last two unless you really know what you
# are doing - there is more information below.
# diff, cpio and find are required for reflash and turnup ram.
# Removing these probably leaves the system bootable, but standard
# openslug and ucslugc stuff won't work, so only take these out in
# very non-standard turnkey slugos builds.
#
# udev is the default way of handling devices, there is no guarantee
# that the static device table is completely correct (it is just
# known to be sufficient for boot.)
# we'ere still on 2.6.12 devfs....

# kernel-module-netconsole is here because it is small and is
# highly useful on minimal systems (which really don't have anywhere
# other than the network to output error messages!)
# this gets /lib/modules made....
