trinity recommends packages are not installed

[Frank Lienhard]

Hi,

I have several packages from trinity missing in may FAi instalation. 
After some investigation. I found out that the problem seems to be that 
FAl installs additional (to the one from the package config of FAI) only 
packages that are marked "depends" and not the one that are "recommends".
Is there a debconf flag that I can set to change this behavior?
