The other day I upgraded a system by using YUM from Fedora Core 5, to Fedora 8. I don't know whether it was a change in the kernel or a change in the way the Fedora team did something but my hard drives changed from /dev/hdx to /dev/sdx. They were both 2.6 kernels. The change was easily acommodated once I figured out that what had happened and why it booted fine with the FC5 kernel, but paniced with "no root device found" with the F8 one. I only had to change /etc/fstab and /etc/rc.d/rc.local, but I was lucky. :-) Geoff. -- Geoffrey S.
