You can make a local copy of the package and debconf selection states using dpkg and debconf-get-selections command. The debconf-get-selections command output the content of current debconf database.
You will require the “debconf-utils” packages to do that.
$ sudo aptitude install debconf-utils
$ sudo dpkg --get-selections '*' > selection.dpkg $ sudo debconf-get-selections > selection.debconf
Here, “*” makes “selection.dpkg” to include package entries for “purge” too.
You can transfer these 2 files to another computer, and install there with the following.
$ sudo dselect update $ sudo debconf-set-selections < myselection.debconf $ sudo dpkg --set-selections < myselection.dpkg $ sudo apt-get -u dselect-upgrade # or dselect install
If you are thinking about managing many servers in a cluster with practically the same configuration, you should consider to use specialized package such as fai to manage the whole system.
