Do you do a network installation with FAI? Or do you boot a FAI ISO
from USB/CD,....?

This may be because of an unknown hardware device. If you do the
network installation, the ethernet device must be activated. Otherwise
the USB device containing the ISO will be used.
Maybe your ethernet device needs some nonfree firmware, which is not
included into the initrd that dracut is using.

Do you have any more detailed warning/error message?
