You probably want to exclude automatically installed dependencies from the list
of packages, otherwise you lose the ability of the tools to tidy up the things
you're not using for you.
I can't remember how to do it just with dpkg - I have a script that uses
aptitude to get the list of packages for me. IIRC you want an i in the first
column and not an A in the second, so the grep would be
grep i[^A]
I have another script that runs through all installed packages and tries to
mark them as auto installed. Any that would cause something to be uninstalled
are written to a list. This list is then the minimum set of packages to install
to re-create the package collection. Plus you get a system where auto remove
works nicely!
Although one thing you need to watch for is that you don't uninstall something
you still want when removing a package...
I'll dig the scripts out later and post links to paste bin.
