[LAD] Faster boot on Raspberry Pi 4

I'm using rasbian-buster-lite and once up and running the performance is seriously impressive. However it's dog-slow to start up. The last message I see before the greatest delay (about 30 seconds) is: Raspberry Pi service to switch to ondemand cpu governor (unless shift key is pressed) during boot up. I suspect the *actual* delay is connected with networking, but with systemD I'm totally lost as to where everything is, so any help would be greatly appreciated. On the Pi 3 I'm able to get a devuan image, and that's a doddle to sort out, but there isn't an image for the Pi 4 :( -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
