Ouch! It does not work :(

Looks like interface at this point is still named eth0, you can see on
console at boot:

[  OK  ] Started Entropy Harvesting Daemon.
         Starting Initializes Pacman keyring...
[  OK  ] Started Login Service.
         Expecting device sys-subsystem-net-devices-eth0.device...
[  OK  ] Found device /dev/ttyS0.
         Starting Serial Getty on ttyS0...

finally in the journal:

May 24 23:24:27 archiso login[184]: ROOT LOGIN ON ttyS0

sys-subsystem-net-devices-eth0.device/start timed out.
