[systemd-devel] Networkd randomly doesn't configure network

Hi,

systemd-networkd randomly refuses to set up my network card at boot.
It gets its proper persistent name but no IP address is assigned,
regardless of whether I use a static configuration or DCHP. A simple
"systemctl restart systemd-networkd.service" fixes it. I'm using a up to
date Arch Linux and systemd 214.

$ cat /etc/systemd/network/home.network 
[Match]
Name=enp1s4

A debug log of a boot without it setting up the card (it does also contain the log after the daemon restart):
