I've been using RHN to keep my errata updated. Very smartly, the kernel 
updates preserve the previous kernels. Well, I'm starting to get a 
collection of them and I'm sure the kernels are starting to hog 
disk-space - or are they? Here's what I have:

rpm -q kernel
kernel-2.4.18-14
kernel-2.4.18-19.8.0
kernel-2.4.18-26.8.0

There's yet another update available that I've yet to download. Their 
manual isn't clear on how to remove the old kernels and if the technique 
automatically updates Grub or if I have to manually edit the config 
file. Anyone mess with this?

Cheers,
Mike
