Within your "Step by step"
Now we need to make a script.sh file that reflects the settings from the .desktop file we created.
Keep Terminal emulator open.
Right click on desktop in GUI, and select create New->Blank file. Name the file myscript.sh. (no period)
Do not muddle things! If you are in the chroot, remain in the chroot.

I did the enviroment settings for the chroot in "krhowto_2" of the HowTo so that you can use graphical tools within the chroot not only as user knoppix but also as root. Therefore type in your terminal "leafpad", create your file and save it where you need it.
Just create an empty txt file and make your changes. After making changes, save the file to:
/KNOPPIX-DATA/home/knoppix/.config/autostart
Don't edit anything within '/KNOPPIX-DATA/'. '/KNOPPIX-DATA/' is only used by the system to display you the content of the persistent memory. If you miss a file within '/home/knoppix/' in your remastered version, you did a mistake; perhaps you don't store it at the right position or you forgot to run the script "krhowto_4" once more.
