//! The provisioner for platforms that do not have one yet.

|
//!
|

|
|
//! macOS and Windows both need real work here — `utun` plus the
|
||
|
|
//! `SystemConfiguration` framework on one, the IP Helper API and a Wintun
|
||
|
|
//! adapter on the other — and neither is written. Rather than let the agent
|
||
|
|
//! come up and fail obscurely at the first packet, this refuses at the point
|
||
|
|
//! of provisioning and says what to do instead.
