What's the official website for FAI?
What order are scripts executed in?
Scripts are executed in class definition order, and in numerical order within each class.
For example, if the classes FOO and BAR were defined (in that order), and
S30, the order of execution would be:
$FAI_CONFIGDIR/scripts/FOO/S20 $FAI_CONFIGDIR/scripts/FOO/S40 $FAI_CONFIGDIR/scripts/BAR/S30
