A nice little addition to have. :)

I think I understand what you mean, but an example (like *rummages through /var/run/dmesg.boot* the boottrace equivalent of "Launching APs: 1 2 3") may confirm my guess - or the guess of other semicasual readers.

If you have a good example on your mind we can surely merge it in. For the time being, I'll just commit what we have so far.

I meant an example of (what you mean by) "one-shot events". If Launching APs: 1 2 3 is one (is it? you haven't said), and unless someone who already has a 14-current running with more than 1 (v)CPU can add an example with the boottrace equivalent of that message or another suitable one before I can get to setting up a suitable VM to try, I can do that once you confirm it counts as a one-shot event.

"one-shot" in this context means an event that occurs once and does not repeat. So the "Launching APs" event is a good example of this, as would be:

0   44875750         15 init                     init(8) starting...                          1    0.00     0     0
