#!/bin/bash
#
# This script is the first stage in bootstrapping a Slackware build to
# a new platform or architecture.  Running with no arguments builds a
# cross-development environment, then cross-builds a minimal rootfs.
# Once you have this minimal rootfs booted, run stage2 in that rootfs
# to build the rest of the bootstrap packages.
#
# This script assumes that all the needed sources and SlackBuild
# scripts are available in $SLACKROOT/source (below).
# The resulting rootfs will be build in $ROOTFS (below).
#
# Note that SLACKSOURCE_LOCAL is for local SlackBuilds that override
# the official ones, for example, board-specific kernel packages.
#
# You may pass a single module name on the command line to rebuild
# just that one module.  Module names match the big case statement
# below.
#
# For reference, when a package is built multiple times...
#
# foo-host is the "runs on host" part of a standard cross-compiler
# foo-target is the target libraries etc
# target-foo is a cross-built target-native
#
# Note that the "dev" step requires sudo, as it installs special files
# in $ROOTFS/dev/
#
# The routine is:
# - Find the Slackware package source (either in $SLACKSOURCES_LOCAL/
#   or in $SLACKROOT/source)
# - Run the SlackBuild script with "--prep" parameter which unpacks
#   source tarballs, does any patching but does not actually compile
#   (the package source tarball is unpacked into $SLACKSOURCE)
# - Cross-compilation happens in $BUILDDIR
