Yeah, don't start the replica automatically - start cyrus in the script that mounts the filesystem. (you don't _have_ to have start cyrus on boot) Also, see my post the other day and various in the archives about the need to monitor synchronisation and restart sync_client after replica restarts. There's no polite shutdown mode.
