Thanks again Falko ... this does actually make sense to me.
But a question still remains: Must I do this each time I have a kernel update? Such updates are fairly frequent for Fedora (and, I suppose. other distros too, since they share the same kernel). I must assume the answer is yes, though it would be nice to somehow automate this. But I'm looking for some reassurance ...
Also, if the new kernel works fine, I don't see any need to keep any more than one previous version of the kernel in the grub menu.lst, correct?
By the way, "cat /proc/mdstat" shows exactly as in your HowTo, which is exactly what I expected.
