It was posted a week or so ago, but here's what they said:
a) Install one machine with all the packages you like.
b) Get the selection with
dpkg --get-selections > my.selection
c) Install the next machine
Quit dselect after you specified the access method
d) Add the selection from the other machine with
cat my.selection | dpkg --set-selections
e) Run dselect to install the files Or if you need batch mode
mount /pub/debian under /mnt and then
dpkg -iGROEB hamm/hamm hamm/contrib hamm/non-free
I suppose this assumes you're installing hamm (the last command anyway).
What I had done is write a script that would take as input a status file
from the machine I want to clone, the status file of the newly installed
machine, and produced a status file that would cause dselect/install to
install or remove whatever was necessary. This kind of fiddling with the
system makes me nervous, though.
Hope that helps.
