Bring back configurability in expert mode

[Havoc Pennington]

Hi,

Suggestions:

1. Talk about specific features, not "configurability"

2. Talk about root problems and entertain multiple solutions to those
   problems, don't insist on having a particular solution before
   you've adequately characterized the goals.

More concrete conversations are much more useful.

If you talk in terms of user goals and the number of steps/amount of
time to achieve those goals, it's much more productive than talking
about the details of the UI.

A user goal is something like "have a machine containing an OS with
only minimum necessary server packages"

Something like "have individual package selection" is a means not an
end. So is anything that presupposes "the installer" - the whole
installer is a means.

First get your ends, then find the best way to reach them.

The various UI books I've proposed reading are very helpful in
describing a process for this kind of decision.

If you don't start with goals you're never going to be able to
evaluate tradeoffs.

If you have the goal "have a machine containing an OS with only
minimum necessary server packages" then you can make objective
statements about number of mouse clicks, length of time, amount of
knowledge, etc. involved in various means to achieve that goal.
