Control: severity -1 important
Contro: tag -1 unreproducible
In accordance with the severity definitions  I downgrade this to
"important". It does not completely break systemd, we don't enable
networkd by default, and it does not affect every installation (it's
not reproducible on our side yet).
Don't worry, I'm still eager to find out what's happening here; I'll
look at your logs as soon as possible.
