That is the biggest plus.

Sample grub boot file:
root-user*>cat /boot/grub/menu.lst

default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Linux 2.4.19 - Densmore Build
root (hd0,0)
kernel /boot/bzImage root=/dev/hda5 hdd=ide-scsi

title=Linux 2.4.19 - USB modularized
root (hd0,0)
kernel /boot/vmlinuz-2.4.19 root=/dev/hda5 hdd=ide-scsi

title=Linux-SANE - Scanner capable kernel
root (hd0,0)
kernel /boot/vmlinux-sane root=/dev/hda5 hdd=ide-scsi

*names have been changed to protect the guilty.
