# This script is the second 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 sources are installed in
# $SRC (below).  Each build installs into /usr.
#
# You may pass a single package name on the command line to rebuild
# just that one package.
