Yum update on FC5 install new kernel but don't update grub.conf

[Ambrogio]

Hi all,

yesterday I was able to update my Fedora Core 5.

For first I updated yum
May 08 12:28:41 Updated: yum.noarch 2.6.1-0.fc5

After that I run the yum update --exclude=openoff* and in the log I
found:

May 08 13:44:00 Installed: kernel-devel.x86_64 2.6.16-1.2111_FC5
May 08 13:45:04 Installed: kernel.x86_64 2.6.16-1.2111_FC5

In the same time yum removed the older kernel.
The query in the rpm database first of update was

kernel-2.6.16-1.2080_FC5.x86_64.rpm
kernel-2.6.16-1.2096_FC5.x86_64.rpm
kernel-devel-2.6.16-1.2080_FC5.x86_64.rpm
kernel-devel-2.6.16-1.2096_FC5.x86_64.rpm

and after the update is

kernel-devel-2.6.16-1.2111_FC5
kernel-2.6.16-1.2111_FC5
kernel-devel-2.6.16-1.2096_FC5
kernel-2.6.16-1.2096_FC5

The problem is that grub.conf is unchanged, and in the /boot directory I
don't find nothing about the 2111 kernel, but I find all about the 2080
that I think are to be removed.

Someone is in the same situation?

The rpm -e of all about the 2111 and the rpm -I of the last kernel is a
good solution?

Tnx
 Ambrogio

P.S.
Why yum is removing the older kernel?
