journalctl -p warning lib/systemd/system/plymouth-start.service:16: Unit configured to use KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update your service to use a safer KillMode=, such as 'mixed' or 'control-group'. Support for KillMode=none is deprecated and will eventually be removed. Посмотрел в федоре, там стоит KillMode=mixed установил у нас, dracut -f, ошибка пропала.
