When doing a scripted install it might be useful to create additional user accounts. You can easily do this with the following command:
/usr/sbin/useradd -m -p ‘\$1$ZRo.R0\$1Lk8iA0AaqVFlojm.BTmr/’ -c administrator -g users -G users -d /home/administrator -s /bin/bash administrator
The “-p” value is the encrypted password. You can create them by using the tool “grub-md5-crypt” on a linux box. Just type “grub-md5-crypt” and type your password twice and it returns a md5 encrypted password which you can use in your scripted install. Keep in mind that there can be special characters in your password, if you do a scripted install this will be misinterpreted and you these characters need a preceding “\”.
