Decent solution, but I'm going the way of the ThinkPads now, and it seems like raspiblitz is ARM only, right?
Discussion
The name is biased, but the #Raspiblitz scripts run on anything Debian compatible on aarch64 and amd64 including Thinkpads:
https://github.com/raspiblitz/raspiblitz/tree/dev/alternative.platforms
you can find prebuilt images too.
If would prefer more manual work see: https://v2.minibolt.info/ (built from the Raspibolt guide)
Oh, that's good to know, thanks. I'll try again when I'm back 🫡
