boting straight into firefox

[Aryeh Friedman]

I am setting a read only kiosk (it displays various web pages
progmatically and has *NO OTHER* function) and security is not a
concern because the hardware is locked away and need to find the most
hands free way method of going from power on to full screen
www/firefox.... is it sufficent to have a su to a non-root user and
then run startx in /etc/rc(.local) [I have a custom /etc/rc so I do
not need rc.local)
