Description of problem:
Yesterday I fetched the latest kernel RPM to upgrade my Redhat-9 installation. I
installed the kernel with RPM -F and everything went fine, except that on reboot
X did not run because the NVidia kernel module was out of sync. To reinstall the
NVidia module would require the kernel sources that I had not available just now.
No problem, the kernel upgrade was just for fun, not because of a real problem I
had encountered. The fix should be easy: just downgrade to the old kernel. rpm
-F doesnt do this, so I did rpm -e --nodeps kernel. This caused the first
problem: grubby complained that it could not find a valid template. The problem
persisted when I reinstalled the old kernel with rpm -i kernel....
Inspecting the grub.conf file revealed that there was no section for the
kernel, so a reboot would fail. I fixed this by hand, but am still unable to
perform an automated kernel upgrade.
I think that this is bad behaviour:
1) There is no real need to touch the grub.conf file at all. Just set a link to
the kernel image that should be booted.
2) If the grub.conf file is touched for whatever reason, grub.conf should be
considered a config file that needs a backup.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. upgrade kernel with rpm -F kernel...rpm
2. uninstall kernel with rpm -e kernel
3. reinstall older kernel with rpm -i kernel...rpm
Actual Results: damaged grub.conf file in /boot/grub
Expected Results: valid grub.conf file
Additional info: none
Same problems here.
In my case it had even more annoying consequences. Even with a reconstructed
grub.conf file (I think I reconstructed it correctly), the machine won't boot.
It simply stops at "GRUB". I need to use now a boot disk. Do I need to
"revalidate" my grub configuration, somehow? (Something in the spirit of 'lilo -v')
I don't know how to get this repaired. I am a little bit afraid to update the
kernel now and discover that it only makes things worse...

I am glad to see that the problem has been identified but it does not solve the
consequences of this bug for me:
I have a non working GRUB because of an unsuccessful upgrade of the kernel (my /
partition was too small). I tried to recreate the grub.conf file (and I think I
did it right) but still, I can't reboot the machine. It says 'GRUB' and freezes.
What am I supposed to do?
