Arbitrum Nitro v3.6.6-rc.1

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.6.6-rc.1-6e3aba7
This Docker image specifies default flags in its entrypoint which should be replicated if you're overriding the entrypoint: /usr/local/bin/nitro --validation.wasm.allowed-wasm-module-roots /home/user/nitro-legacy/machines,/home/user/target/machines

If you're running a validator without a split validation server (this will be true of most validators), you should instead use the image offchainlabs/nitro-node:v3.6.6-rc.1-6e3aba7-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.
