This option allows users to suspend execution of the cloud-init provisioning until a valid network is detected. This detection is currently done through requesting a DNS lookup for one of the Clear Linux NTP service IP addresses (this is a RR record, we don't actually look at the result). This lookup is not infinite. After 5 minutes, the wait exits no matter what even if there is no network detected. The option can be provided manually. `packages` and `package_upgrade` options *imply* this option, but one can explicitly disable the wait by providing it early in the cloud-config file with a value of `false`. The wait routing is active - it will retry relatively quickly to detect an active connection. Any failure will result in another retry. In a fully private network without public DNS, this will not work. The DNS hostname used for testing can be manipulated through the `-with-dnstestaddr=<hostname>` configure flag. You shouldn't put an IP address in here, since that fully disables any network testing.
