In the past we've always had one.  Not quite as advanced a one as
you'd like -- /etc files and kernel configuration are still (rightly)
left to the human administrator.

I encourage you to submit the name of an OS in which non-trivial OS
upgrades are this automated.  I've not met one in the last 10 years,
but maybe you have.  If so we'll look it over for ideas. :-)
