Setting the listen port for keepstore through the legacy config doesn't seem to work, it seems like instead it randomly picks a port to bind to from InternalURLs and if it is in use, it fails, and (in arvbox) it goes into a crash-restart loop until it happens to picks the 2nd port that's still available

Looking at the code, it just adds the legacy "Listen" to InternalURLs, for that to do the right thing, the keepstore InternalURLs needs to be empty to start with.

In getListenAddr in lib/service/cmd.go, it has different behavior depending on the text of the error, in particular, if there are two ports defined for the same host (eg 25107 and 25108) it will fail if it can't bind 25107 and not try to bind 25108.

            continue
        } else if strings.Contains(err.Error(), "address already in use") {
            return url, err
