building package list fails

[Frank Lienhard]

I'm trying to install debina squeeze with Trinity as DE.

I generated a packagelist this way from an example client:

aptitude search . | grep ^i | grep -v '^i A' | awk '{ print $2 }'

and I used that output to generate a class for the package_config, but I 
end up with less packages installed (e.g. missing kdm-trinity and a 
xserver at all).

I found out, that the problem seams to be that additional packages are 
only installled, when marked as "depends" but not when marked as 
"recommends".
Is there a way to tell FAI to install the "recommends" packages also? 
(or is that the "wrong" way to do it?)
