This
prfix the way we handle chain-spec generation using an external cmd (not the default build-spec from the node). As you may already know, runtimes for polkadot, kusama (not rococo) and other system parachain were moved tofellowshiprepo so we can't build anymore chains like polkadot-local or kusama-local from the polkadot binary. A new tool is in progress in this pr and a temporary tool was introduced here. This changes in zombienet allow to use the latest tool and continue supporting spawning chains likepolkadot-localorkusama-local, with the requirement of have this external tool ready to use (for k8s/podman the tool should be included in the pods)In the future we may need to change ir again to support the final tool developed for generating chain-specs.
