Changing default kernel

[Danielb]

I've been downloading the new kernel versions as they come
out for my version of Fedora Core 2. They seem to load
fine, how do I change my boot loader (GRUB I think) so that
it loads the latest kernel version by default? As at the
moment it loads the kernel version that came on the DVD and
I have to manually select the newer version(s) if I want to
load them.

Cheers,

Daniel

Normally when you upgrade a kernel, grub should change to select the
newer kernel. However...

su
vi /boot/grub/grub.conf

There is a line which says "default=x" (where x >= 0)

Change this to

default=0
:wq!

and that's it. It will always default to the kernel at the top of the
list.

I would just copy the existing section with the old kernel and
replace things which have changed

[root@rubikon ~]$ cat /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this
# file
#boot=/dev/hda
default=3
timeout=10
splashimage=(hd0,1)/boot/grub/splash.xpm.gz

# New kernel
title Fedora Core (2.6.6-1.435.2.3)
         root (hd0,1)
         kernel /boot/vmlinuz-2.6.6-1.435.2.3 ro root=LABEL=/ rhgb quiet
         initrd /boot/initrd-2.6.6-1.435.2.3.img

# Original kernel
title Fedora Core 2 (2.6.5-1.358)
         root (hd0,1)
         kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/ rhgb quiet
         initrd /boot/initrd-2.6.5-1.358.img
title Windows XP Professional
         rootnoverify (hd0,0)
         chainloader +1
