I want to use yum. It will download package from repositories.

I know it depends on packages that I have installed.

How could I calculate the space needed ?

My disks are almost full. I would like to know how much data (films, music...) I have to put on DVD. I know I should backup everything but I'm too lazy. –  Luc M Dec 31 '10 at 2:41

If you use preupgrade it will do all the hard work for you, and download a local repository of what needs updated. It will calculate what is needed and let you know if you need more space.

It will also use anaconda instead of yum though. –  Ignacio Vazquez-Abrams Dec 31 '10 at 2:35
