# Go 1.18 and newer automatically embeds vcs information if the go module being built
# belongs (upwards) to a git repo. In this case, that repo is the buildtooling repo, 
# which is problematic. Given these binaries are built from different banches,
# the local dev branhc on PRs and `main` later, the VCS info will change between
# builds, making builds quite difficult to reproduce. That would require that the presubmits 
# knew the future commit that might be created if the PR gets merged.
# Ideally this go module would live on its own repo, so all builds can be undoubtely
# linked to a particular commit of that repo and become independent from the build tooling repo.
# As an alternative, we don't include VCS info in the binary.

# This project is a bit of odd ball when it comes to using the standard makefile targets
# - the image builds are release branch aware but the binary is the same across all versions
# - there is no clone of source since the source for the bootstrap exist in this repo already
# - go-licenses supports only HTTPS URLs so a temporary git repo is created in this project root
#   to add the https origin
# - REPO target is overridden to create empty folder
