Chapter 3. Kernel Upgrades

initrd /initrd-2.4.21-32.0.1.ELsmp.img

In this example, the "default" attribute is set to "0" which means that the

2.4.21-32.0.1.ELhugemem kernel will be booted. If the "default" attribute would be set to

"1", then 2.4.21-32.0.1.ELsmp would be booted. After you installed the newer kernel reboot the

system. Once you are sure that you do not need the old kernel anymore, you can remove the old

kernel by running:

# rpm -e <OldKernelVersion>

When you remove a kernel, you do not need to update /etc/grub.conf.
