Just to add a data point: Buster IoT image on uSD card...

Startup finished in 10.915s (kernel) + 1min 961ms (userspace) = 1min
11.877s
graphical.target reached after 1min 668ms in userspace
That's odd -- Did I leave the LXQT image in the board (I have uSD for
both IoT and LXQT)

Hmmm, looks like I need to attach an HDMI cable and monitor to
