Lazyweb: Does this trick exist?

[Walter Lee Davis]

Is there a way with aptitude or apt-get to export the entire list of what you've currently installed on an Ubuntu box in a format that would make sense for recreating that box elsewhere?

I've read about doing such things with http://devstructure.com/blueprint/

but in practice I usually end up building a new one with something like chef then using that for reproduction.

you can try

dpkg --get-selections

this will generate a list of all currently installed packages

dpkg --help for more options

that will give you an entire list of all local packages

Thanks! Is dpkg interoperable with Aptitude?

[Rodney Oliver]

hmmm, not sure how you want the two to work together. dpkg will not resolve dependencies automatically like aptitude will. You could -

use dpkg to get a list of packages and then in a bash script feed the list to aptitude or apt and let it install them

Ya. You could just "dpkg -l > packages.txt" open it in open office calc. Cut out the column you want. Then fill in "sudo apt-get install" and copy the text into a script. You could make it one line... but I think that would be to much for a single apt-get line. Low tech solution that I did myself once.

If you work with virtual machines, http://www.vagrantup.com/.

dpkg --get-selections > package_state.txt

dpkg --set-selections < package_state.txt ; apt-get dselect-upgrade

That won't do anything WRT configuration files. That's on you/chef/whatever.
