Comment 12 for bug 1549473

SSH to finally learn how to pick up addresses later is a long time demand for ssh to do that.
But it is a demand for an upstream feature IMHO.

I know it can thse day's re-pickup adresses that it lost:
- I have a KVM guest with one interface and I have set up ssh listen to only interface 192.168.122.221
  ListenAddress 192.168.122.221
- All normal/fine.
- If I take away the Network device it doesn#t work (obviously)
- If I attach the device ssh without being restarted works again.

But the problem here as already takled about is the fatal-fail of ssh to start if the ListenAddress not exists at the time.

And network-online.target might be a help for some cases, but not e.g. for networks added much later (like my virtual network example).
When I say this is a demand to upstream SSH for a long time I really mean it - this is in Ubuntu for a decade in bug 216847 and for like 3 years in upstream SSH.

I think this bug here should be used to change it to network-online.target if that really helps some cases.
The old bug I referred will continue to track until upstream implements IP_FREEBIND or any other late pickup tech (like listening to netlink events).
