Hello,

As I explained before, I installed 5.3.1 more as a playground to see and experiment with a lot of programs.

However the "Create a persistent KNOPPIX disk image" which I called before "persistent home" is much more than a home directory on hard disk.

I do find myself much more using the knoppix instead of the ubuntu boot system. I didn't realize before but knoppix present an ideal backup system.

The knoppix.img created by selecting the persistent disk image, was originally set by me to 170MB. I created a new one of several GB. From time to time I do make a copy : sudo cp /media/sda2/knoppix.img /media/sda3/backup.img

Experimenting with adding things now , changes this image, and if I get a problem I rename my backup.img to knoppix.img , rename the first knoppix.img and because I have in my Ubuntu, /boot/grub/menu.lst for the kernel parameter of the knoppix title the option home=scan , I am back to my previous setup.

The original knoppix system on the hard disk remains unchanged; a copy of the live dvd ,and the partition it went to with the tohd= parameter is even protected, I mean read only.

This means that taking a backup of my system is quickly done , it depends on how big you make the knoppix.img file. Do not forget that this file has to be on another partition than the tohd= partition.

This UNIONFS file system used by knoppix is a beauty.

Because I do have Ubuntu and Knoppix on my system, and able to change anything in one system using the other I feel at home with my PC.

Its a lot of fun to experiment on a system with available and installed programs, without fear.

Lucien.
