"GRUB is a bit easier to administer because the GRUB loader is
smart enough to locate the /boot/grub/grub.conf file when booting.
An administrator only needs to install GRUB once, using the
"grub-install" utility. Any changes made to grub.conf will be
automatically used when the system is next booted. In contrast, any
changes made to lilo.conf are not read at boot time. The MBR needs
to be "refreshed."'
