Hi, I upgraded from 1.2 to 1.4 and tested a playbook. I had to accept all ssh connections once again. "The authenticity of host 'foo (10.10.20.60)' can't be established." What change caused this? Marc ---

I'm /root/ user "foo" (and ask me why ...) and formerly ansible (1.2) has used /root/.ssh/know\_hosts, now (1.4) it uses /home/foo/.ssh/know\_hosts and this was quite empty till now. I copied the know\_hosts over to my $HOME. Marc
