I think minimum disk is not possible to encapsulate without a formula,
because at the lower end modern RAM requirements introduce a very large
percentage error because of swap sizes. Eg 8G of disk could have

if you want to use hibernation. Generous RAM and miserly disk makes
sense in a lot of virtualised desktop situations.

So, as an example and with some explanation: 4G+3G+125%*RAM ?

I am guessing the equation used by the installer is more complicated,
but I couldn't easily find it in the ubiquity tree.
