[Lug-nuts] Fingerprinting

I recently had some issues with an old install, fc 25, and espeak. As a longer term solution, I'll upgrade the OS. But, I got some nice AI help in fixing my current install in the meantime. Although some sequences were out of order, and things like that, given the different functions involved, it saved me a lot of reading and research. But, I'm digressing. During the troubleshooting process, it occurred to me that it would be nice to know what my settings had been and how the espeak app was functioning before it just stopped, for no apparent reason. I was wondering if "fingerprinting" an app on the system is a common thing, or just too much effort to get anything useful in the end, and what other people are doing.
