What is different from a security update, to a system that slowly
trudges along from version to version... auto-magically?

That slowly trudging along is similar to what I use cron-apt for on my
"perishable" systems. I use them as a lethal gas indicator. I then go to
these machine and figure out what went bad... and prevent these problems
from occurring on the Real machines. Tell, me what I am doing wrong? I
dist-upgrade everyday on the perishable systems... and usually at least
weekly on those machines that need uptime and availability... but also
need to be uptodate.

I still wonder, if what you are prescribing is a terrible thing to do,
when the ability to have what I do be exceptionally possible overall.

Multi-Leveled Automated Build Systems keep sounding better and better.

Dev->CVS/ARCH/SVN/BK/PVCS->MileStone \

All with controllable and automated rollout with approvals, set tasking
and so on.
