The description sounds good. One question that came to my mind - what can I
do, if the new kernel does not boot, i.e. how can I return to my old
kernel? Can I just boot the old one using amiboot and the old vmlinuz file
on my Amiga partition (are the appropriate modules, config and system map
still there)?
