Is there any set of command-line options that will let me `aptitude dist-upgrade` so that it will add any packages necessary to upgrade existing packages, but not remove any currently installed packages?
You could run `aptitude dist-upgrade` and use the list of packages to install with `aptitude install <packages>` ... If you are only concerned about a small number of packages, you could use `aptitude hold <packages>` which tells aptitude never to change those (until you tell it to do something else with them)
