Replicating packages on Debian

[George Nicol]

1) On machine #1:

    dpkg --get-selections > packages.txt

    This creates a list of installed (and removed) packages.

2) Do a base install on machine #2.

3) Move packages.txt to machine #2.

4) On machine #2:

    dpkg --set-selections < packages.txt

5) On machine #2:

    dselect install

6) Bask in the light of your newly cloned machine.

One limitation: If you are running something old, then your packages.txt
will not point to the right version of the packages. If you are working
with a recent version of your distro, then this is not a problem.

Similarly, "backup ubuntu/debian package selection list":

Not what you're looking for, but may be of interest to ubuntu folks or
those (like me) who have been faced with installing where the user has
only a dialup connection (56k paid for, ~24k delivered):
