I'm guessing most of you here probably observed this behaviour with dnf when FF is upgraded. Even after FF restarted, dnf needs-restarting reports that it needs restarting. Does that sound like a bug or is this somehow intentional?

I'm seeing this in f29 and previous releases are the same. Once I upgrade to f30, I'm planning to open a bug on this if it's still the same, unless someone tells me this is how it's supposed to work.

I see the same behavior (F29). However, "sudo tracer -ea" doesn't complain about Firefox. The question is which tool is correct. My current guess is tracer.
