Hi, Robert.

I've got a script that will generate a list of packages to 'dselect':

It compares the filesystem 'manifest' of a live DVD with the packages
that are installed on the local system, or the packages installed on two
different hosts e.g. Bio-Linux 8 on "wildcat" vs Ubuntu 14.04:

Extract the tar file and try it out like this:

> rwt017 at wildcat:~/Desktop/dpkg-dsel$ ./dpkg-dsel localhost ubuntu-14.04-desktop.sel
> abyss						deinstall
> acacia						deinstall

This is a list of 'dselect-upgrade' package selections that should be
"installed" or "deinstalled": I use it to audit my Bio-Linux systems.

You can install it, and add any other package selections. You can also
use it to compare the package selections installed on two hosts e.g.

> rwt017 at wildcat:~/Desktop/dpkg-dsel$ ./dpkg-dsel localhost alleycat | head
> 3dm2						install
> account-plugin-identica				install

> xaw3dg:i386					install
> xbrlapi						deinstall
> xfonts-100dpi					deinstall
> xfonts-75dpi					deinstall
> xindy						deinstall
> xindy-rules					deinstall
> xscreensaver-data				deinstall
> xserver-xorg-lts-saucy				install
> zim						deinstall

The results show how to change the first host to match the manifest
selections or the packages that are installed on the second host.

HTH,
