I can't set Knoppix 8.6 to persistence
 

Hello. I've been using Linux for years but I still consider my computing skills rudimentary so I need some help here.

My computer is currently lacking a hard disk and I thought it was not usable until I read about Knoppix - a Debian-based live Linux distro designed to function entirely on removable media, without a HD.

I bought a 32 GB USB stick just for the purpose of installing Knoppix and using it as my main system, but for some reason it doesn't save any data, changes, or documents after I reboot (I came to learn such saving is called persistence). I've found a couple of tutorials on the subject but those are either outdated (e.g. they refer to much older versions of Knoppix, not 8.6) or are too confusing and technical and don't go straight to the point, so I have the following questions:

1. Is there a way to make Knoppix 8.6 persistent?
2. Do I need another media besides my 32 GB USB stick (be it another USB stick, a flash drive, a DVD, or anything else) or is a single USB stick enough to make it persistent?
3. In a positive case, how exactly do I configure Knoppix 8.6 to save everything I do and keep it after reboot?

I am really in the need of a persistent system in the moment so any advice is welcome. Thank you.

From https://ftp.gwdg.de/pub/linux/knoppi...cheatcodes.txt I think I would give knoppix mkimage a try.

My only Knoppix stick, v8.1, has this to show:
