Hi belham2,
The nice thing about DebianDogs, if your hard-drives have the room, and you're
not employing rufwoof's method of booting DebianLive Frugal or fredx181's variation applied to Debiandog [neither of which frankly I've yet gotten my head around] is that, like Puppies, they can be run from a folder. So rather than messing with a system which does what you want, you can:
1. Create a folder named, for example, Test,
2. Copy your "live" or "casper" folder into it,
3. Add another listing to your boot menu which specifically points to it;
4. Boot into it, and experiment to your heart's content.
or, sometime, just add an additional boot menu listing to try out different boot parameters.
No offense meant. I'm astigmatic and recently misplaced my glasses. I can read text on the screen pretty well without them, except that sometimes letters blur together and I have to guess. Thought your moniker was bedlam2 -- which didn't bode well for ever getting things organized.
