I agree that a package-based approach increases the complexity of our
software distribution processes.  I observe, as you do, that we are
already managing a complex deployment environment in which most
large-scale deployments have their own customizations.  Individual
deployments have specific needs.  We offer them monolithic images and
also assistance in creating deployment-specific images.  This
deployment-by-deployment effort increases almost linearly with the
number of large deployments that we engage.  I suggest that a more
sophisticated packaging system becomes useful as the effort expended on
custom image creation reaches a certain level.  It is not clear what
that level is, but I doubt it lies at a scale of deployment much greater
than where we currently stand.
