Updating The Boot Loader

• Once we installed the new kernel and its new modules, we need to tell the boot loader about it.
• Generally, we need to supply the following information:
  • Kernel image file path (e.g. /boot/vmlinuz-2.4.20-8).
  • Partition of the root directory - copy it from the spec of the current kernel.
  • Kernel parameters - may be copied from the current kernel, if it has not changed drastically.
  • Optional initrd file path.
  • Label.
