This was an in-place source update, after updating sources to
main-n269230-f6f67f58c19d. On reboot (after "make installworld"
completed, I see this on the serial console (copy/pasted):

Given suitable clues, I can poke at it a bit -- this is my "build
machine," so it doesn't have critical work to do at the moment. (I
would normally have powered it down for the day: here's no need for
it to be wasting energy.)
Laptops are still building ports under stable/14 -- something seems
to want the llvm17 port, and they have firefox to build, so they
won't be testing CURRENT/head for a while, yet.
Peace,
david
