Gary, computers are hard and shouldn't be used by retired folks. :) Run it like below, it will load last. Use AI for docs - much easier and faster than our brains. Type=idle Behavior of idle is very similar to simple; however, actual execution of the service program is delayed until all active jobs are dispatched. This may be used to avoid interleaving the output of shell services with the status output on the console. Note that this type is useful only to improve console output, it is not useful as a general unit ordering tool, and the effect of this service type is subject to a 5s timeout, after which the service program is invoked anyway. https://www.freedesktop.org/software/systemd/man/latest/systemd.service.html Kevin

I upgraded to Fedora 43 on the Thinkpad. It seems to work well! I do have the Temurin Java repository activated. -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

Fingerprinting
by Gary 19 Oct '25

19 Oct '25

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.
