Console Security 8.10 Server guide - password protecting Grub in recovery mode

[Miggleness]

Binary package hint: ubuntu-docs

I was going through most of the Ubuntu 8.10 Server guide. I went through the steps in password protecting GRUB when going into recovery mode. The online guide (https://help.ubuntu.com/8.10/serverguide/C/console-security.html) was lacking as I wasn't able to password protect recovery mode after following the listed steps.

I found this site (http://www.markmmanning.com/blog/2008/07/password-protect-grub.html) that had a more complete documentation on the topic. What's missing is that the the line "password --md5 <hash-key>" should also be added in the recovery mode in the GRUB options list at the end of /boot/grub/menu.lst

i.e.
title Ubuntu 8.04.1, kernel 2.6.22-14-generic (recovery mode)
root (hd0,0)
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=43ad544e-1e1a-4511-99de-fc1c8a9fea7c ro single
initrd /boot/initrd.img-2.6.22-14-generic
password --md5 $1$Yozqb$OIKAYGPKQJfi2U9y/yDG30 <<--- Add here
