upgrade of etch beta to current level
First apt-get update; apt-get upgrade; apt-get linux-image-2.6.18-amd not
aptitude apt-get. I made your mistake earlier and couldn't get beyond
2.6.08 and you should not ever get offers to delete running kernels if you
do this right. I did get a message that modules for my new kernel were
being deleted but upon reboot found the message to have been eroneous.
