I ran into a serious problem on my desktop (I gave the command authconfig.gtk with openldap checked which had the effect of stopping the machine booting) so I burned a Fedora-7 rescueCD and tried that, but it seems I was then supposed to insert the system DVD. Actually, this machine didn't have a DVD reader, so that was out. But it left me wondering what the purpose of the Rescue CD is? I had assumed it was a Knoppix-like CD, but it appears I was mistaken? I would have thought if I had the Fedora DVD, and could read it, I could just enter rescue mode with that? [I solved my problem by using a Knoppix CD, and deleting all mention of ldap in /etc/nsswitch.conf . I'm amazed that one word in that file can stop Fedora booting.]
