Well a DVD holds about 4.4G worth of software so.....that's a good indication of size I'd say. If you boot into GUI and run the script from there you can copy and paste error messages. What you've posted rings no bells with me.

I wonder if it would be possible to send me an .iso of the Linuxtag dvd or let me dl it so I can roast a few copies for those of us not fortunate enough to make it to Linuxtag? Thanks.
