Well, doing it via aptitude and just considering the ~i packages is
likely to not produce a copy of the system.  Just installing those
packages will pull in not only the 'depends' but also the 'recommends'.

Personally I would do both :-) (all of this is untested so please take

On the source system:

 # dpkg --get-selections > dpkg_selections
 # aptitude search '~i!~M'|sed -e 's/ \+/ /g'|cut -f2 -d ' ' > aptitude_selections

On the target system:

 # dpkg --set-selections < dpkg_selections
 # apt-get -u dselect-upgrade
 # aptitude --schedule-only markauto '~i'
 # aptitude --shedule-only markunauto < aptitude_selections

You probably should start the visual interface of aptitude afterwards to
make sure it worked out alright.

Software is not manufactured, it is something you write and publish.
Keep Europe free from software patents, we do not want censorship
by patent law on written works.

Programs should be written for people to read, and only incidentally
for machines to execute.
