minimize.sh is breaking Salt installation.

I am noticing that since 29bff65 the Salt installation has been breaking. It seems to remove packages like python yaml (which Salt depends on)...

    virtualbox-iso: Removing linux-server (3.13.0.32.38) ...
    virtualbox-iso: Removing python-crypto (2.6.1-4build1) ...
    virtualbox-iso: Removing python-jinja2 (2.7.2-2) ...
    virtualbox-iso: Removing python-m2crypto (0.21.1-3ubuntu5) ...
    virtualbox-iso: Removing python-msgpack (0.3.0-1ubuntu3) ...
    virtualbox-iso: Removing python-yaml (3.10-4build4) ...
    virtualbox-iso: Removing python-zmq (14.0.1-1build2) ...

It seems to be the "deborphan" process that causes the fuss. I made an issue with salt-bootstrap to see if I can get a consensus on what is the core problem here... saltstack/salt-bootstrap#484
