Description:

I have a netctl@ethernet-dhcp.service enabled which fails to start at boot due to:

Jun 19 08:57:22 network[478]: Starting network profile 'ethernet-dhcp'...
Jun 19 08:57:28 network[478]: No connection found on interface 'eth0' (timeout)
Jun 19 08:57:28 network[478]: Failed to bring the network up for profile 'ethernet-dhcp'
Jun 19 08:57:28 kernel: e1000e: eth0 NIC Link is Down
Jun 19 08:57:28 systemd[1]: netctl@ethernet\x2ddhcp.service: Main process exited, code=exited, status=1/FAILURE


Once booted, the unit can be started right away with
$ netctl start ethernet-dhcp


Might this be a connectivity problem? Once the net is up, I experience no problems. I also checked the cable and it is plugged in orderly. :-/


Additional info:
* package version(s)
netctl 1.20-1
systemd 242.29-1
linux 5.1.11.arch1-1

* config and/or log files etc.

Steps to reproduce:
> netctl enable ethernet-dhcp
> reboot
(I'm sure it's not as trivial as that, but there is really nothing special about my setup here ...)
