Thanks for your prompt replies tkaiser and Igor.
@Igor I am a bit confused by the phrase "wait until next image rebuild which is almost the same as Beta or DIY"
Are you saying I should avoid using the Armbian_5.24.161121_Nanopim1_Ubuntu_xenial_3.4.113.7z image ?.
​"Next image rebuild" would mean a newer beta version, or beta becomes "standard" image, or both ?.
Sorry if these are stupid questions.
