You can save a list of the automatically installed packages on the
original system like this:

aptitude -F '%p' search '~M' > auto-list.txt

Once you have installed the same packages on the cloned system, you can
do this:

aptitude unmarkauto '~i'

aptitude markauto $(cat auto-list.txt)

(I never tried this myself, but I think it should work.)
