  -t is not supported in package_config files.

Possibilities:

* You could look at the install_packages script and add an additional 
PACKAGES type for your use. This will have several implications, 
depending on how complex this is to be solved, maybe Thomas will release 
a new version with this patch  soon

* install the packages you need with a script in scripts (not really 
nice if you have more than a small set of packages)

* Try to use pinning to get your packages installed

P.S.: I proposed it already a while ago, and still believe that it's a 
good idea to put the array for mapping PACKAGES lines in package_lists 
to the actual command that is called (can even be an extra and more 
complex script that wraps the commands) in a file in /etc instead of 
hardcoded in the sources of FAI.
