Tangential, but in case it's useful to anyone else:
until ssh -o ConnectTimeout=2 $host; do sleep 1; done
I do this all the time for hosts where I'm waiting on boot. The timeouts
and connection refused messages serve as counters so I can do other
things while waiting and have an objective measure of whether or not
I've waited too long for a host to come up. Also handy is that it will
automatically reconnect on anything other than a deliberate log out.
