Dear Urs, I successfully built a Scientific-Linux live cd, thanks for your precious scripts and documentations. But when it boots it asks me if I want to activate the firewall, Selinux, create a user and confirm the sound config (it is the same questions it asks when one installs regular Scientific-Linux distribution). Do you if it is possible to avoid those questions ? (Actually I will like to build the same live cd as ftp://ftp.scientificlinux.org/linux/scientific/livecd/55/i386/mini_livecd_SL55_2010-06-17.iso ) Thanks you Regards ----------------------------------------------------- Simon DADOUN LAL, Univ Paris-Sud, IN2P3/CNRS Bat 200 91898 ORSAY France Tel: +33 1 64 46 86 28 Skype: simon.dadoun mailto:[log in to unmask] -----------------------------------------------------
