I have been thinking of writing some sort of utility for Linux that keeps track of all my installed software and configuration. Something that after doing a fresh install I can just run it and will restore my copy of Ubuntu as it used to be before doing the fresh install.

I do not know exactly where to start with this. I know that you can get a list of user installed software from dpkg -i | grep ii.

  • the /var/log/apt/history* files could be of interest. They include any command used to install/update/remove (parse for Command: to find them all). Keeping track of this, as well as file changes under /etc may be enough. I've been considering doing a mail server set up and feeding the /etc directory to a git repo to track what changes are actually made... but somewhat leery since usernames/passwords would be included... still could be useful for the class i teach

Debian and it descendants have a tool that allows you to create simple packages (with just dependencies). It is perfect for this job.

It is called equivs-build (I have no idea where the name comes from). It will create a .deb. You can install it with gdebi

Here is a makefile (you can do it manually if you want. The make file only adds 10% of the convenience, but documents the process.)

#create source
%.equivs-control: src/%.equivs-control
        @echo %linking "$@" from "$<"
        ln -s -t . "$<"

#make deb
%.deb: %.equivs-control
        @echo %making "$@" from "$<"
        equivs-build "$<"

#install one
.PHONY: %.install
%.install: %.deb
        @echo %installing "$<"
        sudo gdebi "$<"

But first you need to install the few tools.

#!/bin/bash
ln -fs -T ../equivs src
ln -fs -t . src/makefile

#install what we need
sudo apt-get install equivs gdebi-core make

A config file src/my-packages_1.0_all.equivs-control

Description: All of the stuff I want installed.
 This is managed by my install script system.

To use: - run shell script (this boots this install system) - run make my-packages_1.0_all.install

Careful if messing with the file names, part is from the Package: line, part is built in to the tool.


There are other configuration management tools that do a lot more, and are worth a look.
