firstboot scripts

Has anyone had any issues regarding adding scripts to the /usr/share/firstboot/scripts directory? I have added a customization script to that directory as the doc suggests, but it never runs. There is only one small paragraph about using scripts with firstboot on page18 in the doc. Is there some other piece of the puzzle I am missing?
