grubby: unable to open /boot/boot.b: No such file or directory

[Thomas Rabaix]

Hello,

I just update my Fedora 8 with yum, and I don't want to reboot it as I
get an error during the update. I cannot easily rescue it in
case of problem as the host is located at a remote location (datacenter).

so the /boot/boot.b is missing, the bootloader is lilo.

How can I regenerate this file ?

I have include more information about my configuration.

Thanks for your help.

Thomas

INFORMATION
============

I have a Fedora 8 :

# cat /etc/fedora-release
Fedora release 8 (Werewolf)

I had updated the system from a FC4 to Fedora 8 a month ago, I just
follow the instruction from the wiki. Everything went fine.

Now today I run the command sudo yum update , I resume the
dependencies to kernel packages :

Installing:
 kernel                  i686       2.6.25.6-27.fc8  updates            18 M
 kernel-devel            i686       2.6.25.6-27.fc8  updates           5.2 M

Updating:

Removing:
 kernel                  i686       2.6.23.17-88.fc7  installed          44 M
 kernel-devel            i686       2.6.23.17-88.fc7  installed          15 M

during the installation I get

The bootloader is Lilo :
