Comment 7 for bug 1870346

No problem; ran this attempt on a Pi3 (just in case you're wondering about any of the timings!) as the Pi4 is currently busy with Core20 duties, but the result is the same so I assume it shouldn't make any difference to the output.

The event at 2020-03-18 19:33:02,502 in cloud-init.log (line 246) looks suspicious to me?

"No network config applied. Neither a new instance nor datasource network update on 'System boot' event"
