Scott -
Yup...I was not paying attention to the link syntax - I do know
better :-).
On the advice of others in the Centos forum, I did the following:
rpm -Uvh --replacepkgs --replacefiles
kernel-2.6.9-100.EL.i686.rpm
redhat-logos-1.1.26-1.centos4.4.noarch.rpm grub-0.95-3.8.i386.rpm
So now I have the following in the /boot/ directory:
drwxr-xr-x 5 root root 9216 Mar 9 10:31 .
drwxr-xr-x 24 root root 4096 Jan 24 08:34 ..
-rw-r--r-- 1 root root 51676 Feb 17 22:41 config-2.6.9-100.EL
drwxr-xr-x 2 root root 1024 Mar 9 10:31 grub
-rw-r--r-- 1 root root 444812 May 5 2007
grub-0.95-3.8.i386.rpm
-rw-r--r-- 1 root root 1343054 Mar 9 10:29
initrd-2.6.9-100.EL.img
-rw-r--r-- 1 root root 13409764 Feb 18 06:25
kernel-2.6.9-100.EL.i686.rpm
drwx------ 2 root root 12288 Jan 12 2007 lost+found
-rw-r--r-- 1 root root 9371 Aug 12 2006 message
-rw-r--r-- 1 root root 9371 Aug 12 2006 message.ja
-rw-r--r-- 1 root root 7919724 Aug 13 2006
redhat-logos-1.1.26-1.centos4.4.noarch.rpm
-rw-r--r-- 1 root root 67797 Feb 17 22:41
symvers-2.6.9-100.EL.gz
-rw-r--r-- 1 root root 770652 Feb 17 22:41
System.map-2.6.9-100.EL
drwx------ 2 root root 9216 Mar 9 10:03 .Trash-root
-rw-r--r-- 1 root root 1538264 Feb 17 22:41 vmlinuz-2.6.9-100.EL
I am not sure of what to have the symbolic link for vmlinuz point
to; vmlinuz-2.6.9-100???
