FROM BASEIMAGE

# If we're building for another architecture than amd64, the CROSS_BUILD_ placeholder is removed so
# e.g. CROSS_BUILD_COPY turns into COPY
# If we're building normally, for amd64, CROSS_BUILD lines are removed

ENV DEBIAN_FRONTEND=noninteractive

# Smaller package install size.
COPY excludes /etc/dpkg/dpkg.cfg.d/excludes

# Convenience script for building on this base image.

# Remove unnecessary packages.
# This list was generated manually by listing the installed packages (`apt list --installed`),
# then running `apt-cache rdepends --installed --no-recommends` to find the "root" packages.
# The root packages were evaluated based on whether they were needed in the container image.
# Several utilities (e.g. ping) were kept for usefulness, but may be removed in later versions.
