So you go for this, compile your own and settle for CLI. Nah, (initramfs) again.
Well having something is better than nothing, right? You settle for
Armbian_21.08.1_Odroidn2_bullseye_current_5.10.60.img .
Yay, it boots! But think you're going to be a smartazz and do an apt full-upgrade? Sure, it works. But reboot... and now you are at (initramfs) again, and dead in the water. Fail.
