When windowsupdate does it, it's more problematic because I have no way of
knowing what machine that is, who's controlling it ... I'm basically relying
on DNS. There's no strong crypto used for authentication there that I'm aware
of. Perhaps I'm misinformed. I consider the use of ssh keys I generated, from
machines I built, to be more trustworthy than relying on DNS as the

That's not necessarily true either. Anyway, my point was, windowsupdate has
been spoofed, and spoofing DNS is easier than trying to spoof or MIM an auth
system that uses strong crypto. It's not perfect, but it's better than
relying solely on DNS.
(I can't seem to find the news article I'm thinking of, but I'm pretty sure
it's out there. I'll keep looking.)

Go read it again then, and spare us all your lack of comprehension.

You did indeed put words into my mouth - you wrote:
Do you even read what you write? How does a host with root access to
an entire set of hosts exemplify the least privilege principle?
when I had NOT drawn any correlation, AT ALL, between the ssh key admin model
and the principle of least privilege. They were two separate topics that just
happened to be discussed in the same posting.
This is my last post in this thread; further flames should be directed
