Well, I have a somewhat narrow pipe to the greater internet so that
impacts me somewhat to begin with. Second, when I'm playing around with a
new release, or trying a new(er) way of setting things up, I may not 'yum
update' right away because I figgure I'm trying to make mistakes anyway
and will nuke and pave the system before making real use of it. I could
also pull the updates in on another system and make a local repository,
there by performing 'yum update' locally, but that is adding another two
steps to the process of finding out what looks right on the hard disk.

I havent forgotten X being client/server. I guess I should have said

You have pointed out one, at least partial, approach working from a
drastically minimal install and using 'yum install' afterwards, using
either self or expert generated lists of applications to choose what to
install. That should work, but isn't _quite_ the point I was working on.
I guess a different way to ask the point is "Is it worth the developer's
time and resources to build an installation wizard to accomplish an
arbitrary install pattern as "yum install" before starting to install any
