I had already implemented the second step (fai-wide), but was missing out
on the first (fai-class specific).

for fai-wide configuration there are at least two options:

static:
- drop a <xyz>.var file into class/

dynamic:
- create a symbolic link <xyz>.var in class/ which points to /tmp/<file>
- write required content to /tmp/<file> during fai execution
