For others that are saying it want update the boot config then you may have something wrong somewhere because it should plain out update it.

We know that it should update the boot config. And under most circumstances, it does. The problem is that under some conditions, while the boot config is updated with the new kernel information, the default= line is changed so that it points at the old kernel rather than the new one. So far, we don't fully understand why this happens. My theory is that it has something to do with manually creating the config file. I have not tested this yet, but I would guess that if you removed the comments at the top of the grub.conf file and then did a kernel update, you would see this behavior.
