In the previous versions, there are some configuration files and log files are still kept under old path for compatibility. It is better migrating to /opt/fluent completely, but we need to consider upgrading from v4, too.
During upgrading from v4, seamless migration can be done by using environment variable to specify the actual path because there is no need to embed specific path to .service itself. It aims not to be confused which configuration file should be applied.
