I agree with Lingxian on that. Log file name is a part of configuration. Having any assumptions about file naming (e.g. based on a type of process that we run) would make it less transparent. In other words, I think there shouldn’t be any automatically generated names.
Another reason: some day we may want to change something else which means we’d get inconsistency around config parameters, some of them are ‘plain’ and some are ‘generated’.

I think regardless of config files this would be a nice addition slightly improving usability.
I see no reason why these specific scripts can’t be added. I’d say go ahead and send a patch.
