Knoppix 8.3

[Capricorny]

I understand what you say but yes: I need to use it without persistence. I normally use a read-only pendrive to be sure that my Knoppix will not be modified or hacked. I don´t use persistence, I only make some minimal changes manually every time I use it (network and some files -openvpn, browser- I include in the pendrive).

Your concern is not an argument against doing what I suggest, rather the contrary. You can set up a persistent store, but you don't have to use it normally. With the NOIMAGE (if I recall correctly) cheatcode, you start without the persistent store, and that would be your default configuration. But you engage the persistent store for doing modifications to the system, like updating modules, tightening security, set up default accounts etc. And then you run the copy-to-flash routine _with_ the remastering option. Your changes will then be rolled into a new overlay, and you can have a new persistent store set up. And when you subsequently start Knoppix without using the persistent store, your changes will be in effect - no changes needed on startup if you use the ordinary configuration. This process may be repeated several times if you need to update your Knopppix - security updates for the browser is a typical reason for having a new overlay created.
When you run without persistent store, you don't need to have the knoppix-data.img file present on the drive. It may be good practice to have it present only when you do system manintenance. If a version then crops up after it has been moved, you know somebody has tried to tamper with your system.

Please tell me more about the "copy-to-flash routine _with_ the remastering option". I don't know how to use it. Thanks for the answer, I didn't know I could do that.
