Another approach is to write a script something like:

==========================================
#!/bin/bash

list=""
list="$list package1"
list="$list package2"

sudo apt_get install $list
===========================================

Keep this in your usual login directory and update it each time you add
or remove packages. Then run it after a clean install.

I've done this for years with Fedora Linux, though now it has a good,
reliable version upgrade in situ process. But, being a belt and braces
type, I still maintain the list on my Fedora boxes (though the command
there is 'dnf install', so it was natural to do the same on my RPi.
