i have to replace
root (hd0,6)
with
root (hd0,5)
and 
kernel /boot/vmlinuz-2.6.10-5-386 root=/dev/hda7 ro single
with
kernel /boot/vmlinuz-2.6.10-5-386 root=/dev/hda6 ro single
in every stanza to make it work again.

i've red the instructions but i simply don't get it. why can't
update-grub just leave my installation alone?
