From: Gordon Messmer <gordon.messmer@xxxxxxxxx>
The rescue kernel can only be used to boot a system normally if
the corresponding kernel and modules are still available. Once
they are removed, functionality is significantly reduced.
When a kernel is removed, check the rescue kernel and remove it
if it matches the kernel to be removed.
The currently running kernel is assumed good, so build a rescue
kernel based on this version as long as it is still installed.
