This account (images) has sudo access to /home/images/script/autoboot.sh
Which allows you to issue the following commands, to change lab boot sequence:

sudo ./autoboot.sh
sudo ./autoboot.sh windows
sudo ./autoboot.sh linux
sudo ./autoboot.sh hda
sudo ./autoboot.sh hda1
sudo ./autoboot.sh hda3
sudo ./autoboot.sh hda6


To create a new configuration edit:
~/script/autoboot.sh

To edit the grub config file edit:
~/script/grub.lst
DO NOT USE A "default=" parameter in this grub config file, the script will add this!!!
AND MORE IMPORTANTLY:
If you change the grub config file, you may need to edit autoboot.sh windows/linux configurations, 
so that the "default=" values match with your grub config file


This account also has 2 symlinks in its home directory to important directories:
images symlink goes to the tftp directory where boot images are stored 
config symlink goes to the tftp directory where grub boot config files are stored [deprecated soon? script removes need for more than 1 config]
