-# This stage actually builds the RHCOS OCI image. However, due to
-# limitations within OpenShift CI, we need to do the following:
-# 1. Disable KVM by using the COSA_NO_KVM env var. This is due to OpenShift
-# CI using the default OpenShift Docker Build strategy, which precludes us
-# from mounting /dev/kvm into the build context.
-# 2. Due to a limitation in the version of Buildah that OpenShift Builds
-# uses (at the time of this writing, it uses a v1.23.z version of Buildah),
-# we cannot mount the build context into the container build (e.g., `RUN
-# --mount=type=bind,rw=true,src=.,dst=/buildcontext,bind-propagation=shared
-# <cmd>`), which would allow it to mutate the build context. This is due to
-# https://github.com/containers/buildah/pull/3548 not being present.
-# For now, this necessitates passing this image into the cosa-build image
-# build below to extract the OCI archive and inject it into the
-# ImageStream. However, once the OpenShift CI system is upgraded to use
-# OpenShift 4.11, we can create the RHCOS image in a single shot via this
-# stage.
