   I would be open to downgrading the permissions check to a non-fatal error message. I suspect we could end up with a lot of situations where CouchDB refuses to start but the ability to modify the cluster file is a non-issue; e.g. it's a single-server deployment, or a cluster where the FDB server nodes are co-located with the CouchDB nodes (and likely able to modify the cluster file themselves).
   
   The situation we're concerned about is where CouchDB is running as a stateless node and only using the local FDB client to communicate with a remote FDB cluster, _and_ that cluster's coordinators end up changing over time, _and_ there's no out-of-band mechanism to ensure the cluster file gets updated on the CouchDB nodes. It's a fairly sophisticated scenario, and I'd be comfortable with CouchDB logging an error message on startup along with some documentation about the appropriate permissions.
