Now that various Ubuntu ISOs has been folded into the regular desktop ISO, how do I install the minimal version which featured in the erstwhile alternate and the minimal ISO?
Minimal CD
Regarding minimal CD, it can install minimal Ubuntu but requires net connection to download even the basic that basic set of Ubuntu packages. And therein lies the problem: I don't have a LAN connection I can use and, even if text-based installers did support wireless connections (they don't, IME), my wireless hardware is a little too new and requires manually compiling and installing drivers.
If you do have net connection and want to install minimal Ubuntu, Minimal CD is the way to go.
