Finally figured it out.....

Was forgetting to change owner back to root. - everything's saved the way it's supposed to be now.

Basically, I built a live-compiler that doubles as a bootdisk for the proggies that I compile to run in ram. I installed gmp-4.2, (for static builds), and upx, (to compress the builds). I added a script to the /etc/init.d folder:

cd /mnt/floppy
./runme.sh

I then used ksysv (init-editor) to add to runlevel 1. Isolinux.cfg edited to default to runlevel 1 with 5 second delay. Desktop accessed by typing knoppix at bootline.

When bootdisk accessed, runs 'runme.sh' on floppy - copies my proggie and needed files to ram, then executes the proggie in ram. - Works great.

The only things I want to change now, is username, and figure out a 'nopowersave' 'noblank' boot option to add to the bootdisk bootline - so screen doesn't go out in 5 mins.

Anybody know a boot option for this? I've tried nopowersave AND noblank (as suggested in another linux thread), but they don't work in knoppix.

Any ideas appreciated.

cheers.
