The non-live installer unpacks RPMs to the filesystem, introducing multiple
layers of indirection that isn't there on the live install which is just
blasting the filesystem image to the device as fast as possible. Enhancing
RPM to be as fast as writing a filesystem image I believe falls far beyond
the scope of this initiative.

It would require not insiginficant changes to comps. For example, we
offer 'Sound and Video' as a group checkbox. There's no good way to make
this checkbox do a reasonably sane thing depending on which of the other
checkboxes you checked (did you check GNOME? KDE? No desktop at all?)

This is a big advantage of the live media; it's not just curated for the
default offering, but gives a good method for any use case to design for
its offering.

Stepping back for a sec, a lot of this would go back to actually designating
what the non-Live media is for. We've *never* done that, leading to it
essentially just being 'a set reasonably comparable to what was on the old
Red Hat Linux CD/DVD.'  I don't see how something with that mantra helps
with our usage cases/target audience, regardless of technical benefits.

One minor issue here is referring to the install disc; I have three
'modern' laptops in my household, and *none* of them came with optical
drives. Obviously, the plural of anecdote is not data, but I think it's
a case we need to have a good answer for, even if it's no better than the
current case for live images where you need some additional tool.
