I know that ssh is smart enough to stay connected (or reconnect), but I am wondering if there is a general rule of thumb to keep in mind when restarting network services via ansible? ie. I am disabling NetworkManager on all systems, enabling the network, and then restarting the network. Any gotchas or anything else to be aware of?

`

# tasks file for disable\_NetworkManager
