Inconsistency between ipfs and ipfs-cluster

I think there’s a slight inconsistency between on of the flags for ipfs and ipfs-cluster-service. In ipfs the ‘-c’ flag is the “path to the configuration file to use” which I would interpret as $IPFS_PATH/config but ipfs-cluster-service the ‘-c’ flag is the “path to the configuration and data FOLDER” ie $IPFS_CLUSTER_PATH

Is that correct or am I interpreting that incorrectly? If it is correct it’s a bit confusing and is there a way to set the equivalent of IPFS_PATH for the ipfs command?

Thanks

Your interpretation is correct.

No, the only way of customizing the ipfs folder is setting $IPFS_PATH, I think.
