I'm not a complete newbie to Linux, but Knoppix will be the first time I've used a live version.

My question is, what is the minimum size needed for a persistent home directory? I'm currently unable to devote much space for this, but would like to retain my settings whenever I reboot. So, how much do I really need?

Thanks in advance for any help you can give me.

I've searched the site, but I couldn't find the answer.
