We actually have this in our current testing environment.
What you typically want is to have two files in your fai/config/ tree, a 
sources.list file and a hook script (at least this is how we solve it). 
The sources.list file should be named after a class, where you for 
example define what distribution to run, and be put in 
fai/config/files/etc/apt/sources.list/, i.e 
fai/config/files/etc/apt/sources.list/LENNY_AMD64.
As for the hook script ours is called 
fai/config/hooks/updatebase.DEFAULT and is a small shell script to say 
the least:

 #! /bin/bash
 
 fcopy -Bi /etc/apt/sources.list

What it does is that it takes the file based on your defined class, for 
example fai/config/files/etc/apt/sources.list/SQUEEZE_X86, and copy it 
to /etc/apt/sources.list on your target system. Thus you can have 
multiple sources.list files aimed at different releases (and 
distributions or architectures if needed).

I hope this answers your question.
