I found a method to do that manually too so I’ll try that.
Now I installed a fresh copy of the RPi image on the second machine. I restored the system no problem and did all my custom config stuff. AdGuardHome won’t recover through Yuno but no problem, very easy to do manually…if I could get the damn app to install.

Apparently the system backup comes with app permissions? Again, this is the new system with 0 apps. No idea why it’s whining about vaultwarden permissions.
