Why do you set this? Doesn't make much sense in my eyes and even nails
the script call to be in the directory with the update files.

Paul already said to use "-i" instead "-U" here to be on the safe side.

Dave Jones recently pointed out here on the list that the
kernel-2.6.9-i686.config is a suggestion and does not necessarily must
match the config of the kernel you installed above. You want an example?

A specific reason why not letting do yum or up2date do the job to find
out whether there is a matching kernel for an update in the updatedir
(which is a repository then)? You then have no need to write your own
logic to determine the right kernel RPM matching your system.
