Disappointing.

[wdt]

You do know, I hope, that the pwr button needs a 1+ second press?
A quick press does not work
Manjaro is a little slow to show logo, if green light is lighted, it is booting
danielt has a git that installs buster (to SD), worked for me (under mrfixit, not manjaro)
The depends can be satisfied under manjaro I think
So far, only manjaro gives decent sleep (I think I've tried all others)
