--- Comment #3 from Damien Miller <djm at mindrot.org> ---
This is the intended behaviour. StrictHostKeyChecking controls whether
ssh accepts a *new* hostkey automatically. It is not intended to
disable host key checking entirely.

I'd generally recommend against doing that, because an on-path attacker
can trivially MITM your connections. If you really want to do this,
then the easiest way is to pass "-oUserKnownHostsFile=/dev/null
-oStrictHostKeyChecking=no" to ssh.
