# Script:  build_installer.sh
# Purpose: Build the Slackware installer from scratch (multiple architectures)
# Author:  Stuart Winter <mozes@slackware.com>
#          Eric Hameleers <alien@slackware.com>
#
################################################################################
#
# Notes: [1] If you want to use your own _skeleton_ initrd (containing only
#            the directory layout plus all the scripts) you just make it
#            available as ./sources/initrd/skeleton_initrd.tar.gz
#
#          The script will look for the directory 'sources' first in your
#          working directory, and next in the script's directory (whatever is
#          found in your working directory takes precedence).

############### Install libraries into installer's filesystem ##################

# We install the library packages and copy only the parts that we need.

# in the code above, it's because this way we don't need to keep up to date with
# any new library names or versions - we either take everything or be very
