# BUSYBOX ALTERNATE CONFIG MINI-HOWTO
#
# Busybox can be modified in many different ways. Here's a few ways to do it:
#
# (1) Emerge busybox with FEATURES=keepwork so the work directory won't
# get erased afterwards. Add a definition like ROOT=/my/root/path to the
# start of the line if you're installing to somewhere else than the root
# directory. This command will save the default configuration to
# ${PORTAGE_CONFIGROOT} (or ${ROOT} if ${PORTAGE_CONFIGROOT} is not
# defined), and it will tell you that it has done this. Note the location
# where the config file was saved.
#
# FEATURES=keepwork USE=savedconfig emerge busybox
#
# (2) Go to the work directory and change the configuration of busybox using its
# menuconfig feature.
#
# cd /var/tmp/portage/busybox*/work/busybox-*
# make menuconfig
#
# (3) Save your configuration to the default location and copy it to the
# one of the locations listed in /usr/portage/eclass/savedconfig.eclass
#
# (4) Emerge busybox with USE=savedconfig to use the configuration file you
# just generated.
#
################################################################################
#
# (1) Alternatively skip the above steps and simply emerge busybox without
# USE=savedconfig.
#
# (2) Edit the file it saves by hand. ${ROOT}"/etc/portage/savedconfig/${CATEGORY}/${PF}
#
# (3) Remerge busybox as using USE=savedconfig.
