Thank you for the tip. I currently solved this without cheating:
1) I use a shared folder on VirtualBox
2) On the main bash I'm running, after the compilation is done I create MyApp folder, and move from the output/images folder renaming 3 files generated.
Simple solution for my dumb question :/
 
 

For anybody reading this: Most of the debugging for your setup routines can be done just by looking inside generated image file.
Of course I have to burn the sd-card and run on actual device at the end...
 

Thank you Werner, that helps.
 
I had a misconception with the namin. "Userpatch" mixed with kernel pathing, "overlay" with overlayfs.
 
After examining the code I found correct keywords for search and found this:
I also recognized from the code that only customize-image.sh is copied to destination and my other files (which I call from it) do not.
 
Now the post you shared comes into play...
 
Thank you again.
 

OK, this was a "memory not enough" problem. Actually I did not need to compile...
 
Please refer to: https://forums.urbackup.org/t/trying-to-compile-the-client-for-armhf-make-errors-out/9400/4
 
Now I can have /etc and /var/log backups of my Armbian devices to my central server...
 
FYI: Next version will support full Linux client image backup. Now I just use "tar" and backup file through UrBackup.

Why don't you say I have to look at the "archives" for focal desktop  

I feel so dumb !
 
After many hours of tcpdump'ing and log tailing I found my mistake... Just to record this unfortunate event:
I first installed pihole DHCP for the exterior network (192.168.100.0/24) then moved to home-network (192.168.64.0/24) side.
On the web interface there is a "Router (gateway) IP address" and my router is in at 192.168.100.2 - I left it as it is  That should be on the same subnet of course  Changed it  and it worked...
 
Sorry for your time
