Hi Mark,

I pretty cavalierly assumed this was possible, and yet I can't find any
evidence that it is.  Most likely even if it is possible it's not portable
or easy.

I don't really know what a good solution is, frankly, which is why I
haven't even looked at trying to submit a patch.  The problem of
authenticating a host that can report different names and addresses is not
easy.  The only solution I can really think of is to have the same set of
keys on multiple hosts.

It would be nice to be able to explicitly run cfagent in a way that it
knows it's on a terminal, such that it asks you whether you want to trust
an unknown host, similar to what ssh does.  There are a couple of ways to
deal with it, but we as a community need to establish a best-practice
method of getting all the keys right, and then modify cfengine if
necessary to better support that method.

with sense, reason, and intellect has intended us to forgo their use.
