For example, what does it look at to produce the following snippet of its output, especially when I ran "sudo akonadictl restart" and that command said Akonadi wasn't running? If it is restarting other associated applications then where are the messages about what it is restarting and whether or not it was successful? You should restart: * Some applications using: akonadictl restart * These applications manually: DiscoverNotifier akonadi_archivemail_agent sudo akonadictl restart Akonadi is not running.First I'd review the man page: DESCRIPTION Tracer determines which applications use outdated files and prints them. For special kind of applications such as services or daemons, it suggests a standard command to restart it. Detecting whether file is outdated or not is based on a simple idea. If application has loaded in memory any ver‐ sion of a file which is provided by any package updated since system was booted up, tracer consider this application as outdated. If that's 100% the case, then it's looking at fairly crude deltas in order to figure out what needs restarting. And restarting a service doesn't change tracer's output. Since it's calculating the delta between last boot and packages updated. Then anecdotally, I've just updated a system, restarted a service tracer has identified (as you have), tracer still tells me that it needs restarting because the calculated delta hasn't changed, despite the service being restarted?It definitely does change tracer's output. I use this on a daily basis. Any time I restart something and check again with 'tracer' it notices and doesn't flag the service or app. I suspect a documentation bug. It doesn't seem to me that it's checking against boot time but against the last time the service or app was updated, which makes more sense.
Yes, but why would it suggest restarting an applications that are possibly not actually running, as the command shows akonadi wasn't running, so why produce a message that it needs restarting?
Just on that front and slightly off topic to this question, I've had tracer tell me I need to manually restart Plasma Shell, how does one actually do that without rebooting the system or without the restart of that forcing a reboot?

Steve
