# FIXME: We need to get an ancient version of oci-runtime-tools because the
#        config.json conversion we do is technically not spec-compliant due to
#        an oversight and new versions of oci-runtime-tools verify this.
#        See <https://github.com/opencontainers/runtime-spec/pull/1197>.
#
#        In addition, there is no go.mod in all released versions up to v0.9.0,
#        which means that we will pull the latest runtime-spec automatically
#        which causes validation errors. But we need to forcefully update to
#        runtime-spec 1.0.2. This is fine.
#        See <https://github.com/opencontainers/runtime-tools/pull/774>.

# FIXME: oci-image-tool was basically broken for our needs after v0.3.0 (it
