#!/bin/bash
#
# This script is the first stage in bootstrapping a Fedora 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 SRPMs are available in
# $SRPMDIR (below) and that there is exactly one rev of each package's
# SRPM. The resulting rootfs will be build in $ROOTFS (below).
#
# Note that SRPMDIR_LOCAL is for local SRPMs that override the
# official ones, for example, board-specific kernel RPMs.
#
# 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/
