Greetings- I have a few custom kernel parameters being passed to a CentOS box via the /boot/grub/grub.conf file. However, if there is a kernel update, and grub.conf is regenerated, how do I ensure my custom parameters are: a. left in place on the older kernels b. added to the new kernel? I would think this should go in /etc/sysconfig/grub but I'm just not finding any documentation or examples of this in my searches. Could anyone offer a pointer? --Tim

I always delete the rhgb and quiet, or occasionally I need to create my own grub.conf, and once I do that, 100% of the time, when I get a kernel update, it sets the default to the last live kernel, not the new one, leaving me to go through manually. mark

I do see an option to grubby, specifically '--copy-default' which appears to do the necessary work. This is called when the new kernel is installed (yum/rpm)? --Tim
