Ná que va, es que realmente me ha pasado. : -P
Te pongo un ejemplo bastante más peligroso:
Los "metapackages"
Ejemplo práctico:
sudo apt-get remove usplash
Los siguientes paquetes se ELIMINARÁN:
ubuntu-desktop usplash usplash-theme-ubuntu
Hasta ahí todo normal, nos quedamos sin usplash y tal, que es el paquete que queremos eliminar. El problema es que "ubuntu-desktop" que también lo elimina es un metapackage, osea, un paquete virtual que en principio contiene:

Solo hemos borrado el metapackage, es decir el paquete virtual, pero no los demás. Sin embargo, apt supone que como el metapackage ya no está, la lista de paquetes reales que representaba ya no son necesarios.
Si ahora haces un "apt-get autoremove" borrará todos esos paquetes. ¿ Te imaginas el desastre ?
, sobre todo a la hora de eliminar.
