I currently help QA team in ISO testing, but I stumbled on a test-case that required some extra research. I just learned about persistence from this wiki page.
Ctrl+F to "Using a loop-back file." Since I will be ISO testing on a Mac, I don't know if it's appropriate to make the file in the root of the partition of my Ubuntu computer.
If the loop-back file is indeed necessary, how can I use it for my Mac computer? If it is as simple as copy-paste, I'll be surprised.
