Anyone know what exactly goes on when yum applies a kernel update? Something automagically edits the /boot/grub/grub.conf file, but whatever is doing that isn't doing it the same way on a couple of different fedora boxes I have.
RPM is doing the heavy lifting. Check the first stanza in menu.lst. RPM uses that as a template.
One box once had Xen installed, but I removed all the Xen stuff because it wasn't very useful on the machine. This box now inserts a new kernel at the top of the list of "title" sections, but changes the default= parameter so the old kernel is the default boot. Another box never had Xen, and when it gets a kernel update, the new kernel is inserted at the front, but the default= line is NOT changed, so the new kernel is the default boot. What the heck is different and how do I make them the same?
Edit /etc/sysconfig/kernel to make all your systems the same.
