Comment 10 for bug 2058976

To be clear, that carrier is set to "failed" when retriggering uevents is not the main problem. The main problem is that after 5-10 minutes, networkd silently takes control again of the ethernet interface. The retriggering of uevents and the reaction on the networkd side is just an indication that it still cares about the interface.

Maybe a better way to check if the issue is around without having to wait for minutes would be to look at /run/systemd/netif/links/* and check if the content still references the removed .network files.
