Ok, my host install FC4 with lilo, so I update to F8. I suppose the
update script from Fedora keep lilo and don't use grub at all.

Now how can I reinstall lilo to make boot.b appears. I have only one
chance :) (remote location)

I am not sure that my system will reboot properly without this file,
am i right ?

Thanks

Thomas
