Hi Plentyn! that's good news! thanks and if you meet Roland send him my very best greetings :^)
If useful, I can share the latest slides I've used in some presentations, in libreoffice format.

Thanks to you and @cpoakes for detailed reports. I haven't reproduced nor investigated in depth, but at first glance it seems there is something wrong with the installer upstream. We haven't touched anything regarding firmware at install in Devuan AFAIK. We'll reproduce this and test to fix, indeed adding an issue on gitlab is way to go for now, tagging it for the RC milestone.
