packages in a fresh install

[Marcelo Chiapparini <marcelo.chiappa@gmail.com>]

Hi!

I am upgrading my notebook. The old one runs etch like a charm. I want 
to run etch in the new notebook too, and to have installed in it exactly 
the same packages than in the old one. So,
1) does exist a file with the information of all the packages installed 
in the old system?
2) is it possible to use this information in the fresh installation on 
the new system?

thanks in advance!

regards

Marcelo
