It sucks having to re-image the whole thing again and again. But being a toy, it is not that bad.
And again, as usual, I had trouble configuring its DNS. I had to connect a monitor to be able to use NetwokManager, even though it uses a terminal interfece nmtui.
I have to say that rpi-imager worked pretty well.
Nevermind, now it is up and running fine. I only have to tweak some things here and somethings there and enjoy my renewed toy whose hostname is kiwi by the way.
