Indeed, this is the most terrifying of messages to ever appear.
You just ran a command across N machines, two of them failed. Ugh.

The *BEST* case is things like e.g. "apt-get update" failing because of
a spurious mirror resolution failure. (Or maybe the UDP DHCP query
failed for one or two or three of your hosts?.)

Choose this path.

(I have no idea of what's best, but almost *anything* is better than
"iterate through hosts and run command".)
