Hi grump,
If not too heavy and free of compromising personal data,i would be curious to check your appimage .
Finding this post add to the funny fact that i helped to test ,use(parport only..) and share my ¨updated¨ puppy linux variant iso;
debiandog rtai here
Could looking at your own appimage give some clues to what should /could be included in it for a possible uspace future puppy linux variant i am thinking of?
