What would cause this message to occur after a fresh loading of FC4 in the desktop mode with SELinux and iptables enabled, and a full yum update? Well over 470 MB of packages were downloaded by yum. Kernel is updated from 2.6.11 to 2.6.13 and there is an SELinux update too. After the update, the system still runs OK, but won't survive a reboot. Since I can't get it to boot, I can't get into the logs to see what went wrong. While I'm waiting for an answer here, I'll probably do a fresh reload of FC4, and then yum the kernel and the SELinux updates separately to see if one of them is the culprit. If not those, then I'll yum the rest and check the logs before doing anything else.
