installing packages from a list.

[Tom Allison <tallison@tacocat.net>]

I have two machines that I would like to have the second one installed 
with the same list of packages as the first.

I know I can find out what is installed by running

 dpkg -l | grep ^ii | awk '{print $2}' > installed_list

But how can I use that list as a starting point to install the same 
packages onto another machine?

Is it:

       dpkg --set-selections < installed_list

or something else?
