[systemd-devel] networkd - how to start service right after the "link configured" stage?

[Peter Lemenkov]

Hello All!
I'm currently doing a great stuff with systemd-networkd but one thing
is holding me back. One of my services is starting too early. I'd love
to delay its startup right after the "link configured" stage.So far
I've got the followng in journal logs:

el7 ~: sudo journalctl -M mycontainer -b --unit="systemd-networkd"

So far I've got few questions:

- Does networkd emit some D-Bus event when the network link is configured?
- If yes is it possible to add a systemd service triggered by this
D-Bus message?
- If no is there a way to start systemd service after the given
network link is configured?
