So the real question is what do we 'suggest' our default install be?
1) Live CD: Can't upgrade, do package selection or specify install method.
Why can't a system that is installed from the Live CD be upgraded?
What would it take to make such an installation upgradeable?
I believe it is reasonable if the upgrade is possible, even if it
requires a separate step after initial installation from Live CD.
[Specifying install method and package selection is a natural for the
Rescue CD; see #3 below.]
2) DVD: isn't live (duh :) but requires DVD burner and drive to do
installs.
In the "first world" a DVD burner is $50 or less and a DVD reader is
$30 or less. In other places (or if those prices are a serious barrier)
then share through a user group or a buddy, or postal mail, etc. Seriously.
The isolated boxes with no DVD also tend to have anemic network connectivity.

and spoon fed them to somebody at 33.6Kbaud.)
