Running Fedora 26 Minimal (20170504.n.1 compose) inside a kvm virtual machine, all goes well.

Using it in a Raspberry Pi 3 model B, the boot process is ok, the system is subsequently functional, but I have an issue with initial setup process: in other words the systemd initial-setup unit fails to start.

Please note that I don't use a screen, but I'm connected to the RPi using the serial connection.

Someone else is facing the same issue? 


Thanks
A.
