In order to effectively distribute sources of CRW, as well as make builds more reproducible, CRW should adopt Cachito. Usage of Cachito with our build system is described in detail here:

• https://source.redhat.com/groups/public/container-build-system/container_build_system_wiki/containers_from_source_multistage_builds_in_osbs#jive_content_id_Cachito_Integration

Additional helpful info can be found in the package-managers section of the upstream project:

• https://github.com/release-engineering/cachito#package-managers

Essentially you specify the top level projects you're pulling in for your image, and with proper dependency declarations, cachito will crawl through the tree and gather all of them, and make them available to your builds. This enables our internal tooling to distribute those sources later.

In order to enable source containers, this should be enabled for all supported streams.
