Did your email agent wrap the above?
In any event, you are specifying a seperate boot partition with the
line 'root (hd0,6)' above, so the next 'kernel' line s/b relative to
that. In other words:
kernel /vmlinuz-2.6.8-1-386 ro root=/dev/hda7
because there is not a /boot directory within the /boot partition,
then the path to vmlinuz becomes relative to the 'root (hd0,6)'
aka /boot partition. I assume your '/' partition is /dev/hda7?
And what is the
savedefault
boot
??
The normal grub install has a few lines of comments above the actual
entries, and I'm wondering where they went.
