just an example...
I have an USB external disk but my laptop is not booting off the USB
disk (I suppose a BIOS bug), so I use a boot CD at start-up.
During upgrade from FC3 to FC4 I fired up the PC with the old kernel
by using CD, I tuned FC4 initrd file by creating a ner initrd file, I
burned a new boot CD and I restarted the machine.
Same with upgrading from FC4 to FC5, but I had to copy vmlinux,
/lib/modules from a working machine and I could re-start the machine
with the old boot CD: and again creating a initrd, burning a boot CD.
