Yes, I wanted to call this out specifically to you, but forgot. I have
been adding this "fix" in my working branch and then removing it before
commits. It has been working well for me.
Without specifying `port=22`, `wait_for` simply sleeps until the timeout.
Until now, it has just been waiting 5 minutes, every time, no matter what the
state of the hosts is.
I have seen others using the following, but I think this wasn't working for
you early on? This not only waits for the port to open, but also for SSH to be
ready to respond.
```
- local_action: wait_for port=22 host="{{ hostname }}" search_regex=OpenSSH
delay=10
```
