I think there is a project that does this, and has been doing it for
quite awhile.  It's called Microsoft Windows.  The problem that this
method poses is that it's very easy to get to a point where you have no
idea what the current real state of your system is.  With the
modularization that already exists and is increasing all the time with
Fedora (and all OS Unices out there really), updates are getting smaller
and more 'directed' and bandwidth continues to increase while the price
goes down.  What would really be the best answer to this would be having
anaconda have the ability to pull down updates from a yum repo during
install, so instead of installing package Z only to have it updated to a
patched version right after reboot, it's all done on the first shot.  If
you maintain a large number of systems, just make a mirror of the Fedora
updates to keep the traffic local.
