Well, I've tried to read (for the past hour) how to correctly use "xdelta3', but the documentation is not very clear in my opinion. The only thing I could get to run is showed in the pic below---and I do not believe it can be right because it took less than 2-3 secs to run, and the resulting 18.03+4.iso is only ~2.8MB larger than the original 18.03.iso.
Yet the .delta is 57MB in size, and when you do it inside a puppy, it definitely takes longer than 2-3 seconds for the delta to apply & then generate the new .iso.
Can anyone give me some hints on exactly what to enter into the terminal? I've tried the "-d" command paramter, and also "djw -S" parameters. (Fred, you out there??, I am in my XFCE-Debian64-build trying to do this)
