Hi,

KNOPPIX configuration, which you find under the label "Save KNOPPIX configuration" saves: /etc/*, $HOME/.*, $HOME/office/*, and $HOME/Desktop/*. You can tell it to not save any of these, when you go through the menus. This information is restored only at bootup, and is modified only when you save a new configuration. Meaning, that every time you make a change to your settings, you will need to save the configuration over again.

Persistent home, which you find under the label "Create a persistent KNOPPIX disk image", saves only $HOME/.* and $HOME/* (everything in your home). You do not get a choice of what is saved and what is not, and you must decide upfront what size the whole thing will be. This image is mounted on startup as an actual disk. This means that any changes you make during your session, will be immediately reflected in the actual image.

If you use both, it is possible to have contradictory information between the two, specifically in the dot-directories in your home. I have not experimented enough with this, to know which will take precedence, but I suspect the persistent home will.

Do you have a question about something more specific?

HTH.
