I have create the following file in /etc/live/config.conf.d/user.conf:
LIVE_USERNAME="tux"
LIVE_HOSTNAME="tuxland"
LIVE_USER_FULLNAME="Tux User"
However, when I boot the ISO I cannot even get to the tty since there is immediately displayed the message "Authentication failure".
The above is being created via a hook into config/hooks/live/
What am I doing wrong? Is it the naming convention of the conf file?
