Hi. I can't tell you an easy way to get a list of all installed
packages in a file. The aptitude program groups packages by installed
UN-installed and a few other categories. Aptitude installs packages that
are suggested like dselect. As far as I remember, apt-get won't.
apt-get install aptitude
If you add the -u option to your apt-get upgrade command, it will show
you what will be done before it does it.
apt-get -u upgrade
Also, if you use aptitude for package management you will see what will
happen before it does it.
