I think most developers like to know if their stuff is broken, and to have the logs. That’s why I bring it up. Also other people might try it and find something else, that is different than I found.
Rather than staying stuck if anyone else hits this issue, I suggest people do a full uninstall, zip or tar up the old logs in case they are useful to the developers, and then remove /opt/couchbase completely, to ensure a clean 4.0 RC0 experience.
