Serious problem with kernel update

[Richard B. Pyne]

There is a VERY SERIOUS problem with kernel updates, which I 
have brought up in the past and I thought had been fixed!

NEVER, under ANY circumstances should a lin of a kernel remove 
the current (or any other) image from the boot directory!!!!!

This creates a very real, if not likely scenerio of making a 
machine not bootable.

I just did a lunar update on one of my machines only to discover 
that it had completely wiped out the prior (running) kernel.
