# Helper Makefile to build base image
#
# - local build / debug:
#    make base-image
#
# - release packaging:
#    make base-image package=yes compress=yes build_profile=release
#
# - cross build:
#    make base-image build_arch={aarch64 | x86_64}
#
# When building without packaging, dive can then be run with:
#    dive -i nix/ [container name]
