OK... so it's a bit more complex... A nice link would be Bob's Anaconda
HOWTO (http://www.sd.no-ip.biz/code/aurora/).
Over there you have some other nice links...
If you need more info... google 'round...
For CD generation I personaly use a small script.
The script expects to have in the current directory the i386 and SRPMS
directories.
If anyone can give me a review on it, i'd really apreciate-it.
If it's OK then I'll start work on a GTK2 based anaconda customiser.
Don't forget to check the export's at the begining of the script.
( The comments with a plus apply to fedora core)
