 Desde alli se debe escalar en privilecios con un sudo y depsues lanzar el instalador:
-coreos-install -d /dev/sda
+coreos-install -d /dev/sda -c cloud-config.yaml
-se le puede pasar alguna informacion de configuracion de ser necesario asi:
+Es muy importante pasar el cloudconfig para no enrredarse  despues con la autentificacion.
+Aqui se muestra como: https://linuxconfig.org/how-to-perform-a-bare-metal-installation-of-coreos-linux
+Y para poder poner una ip fija se puede mirar aqui:

+Reiniciar todos los nodos y comprobar que no se vean errores.
+Para ver si el servicio etcd2 esta ok en todos se puede usar:
+systemctl status etcd2
+La salida debe ser asi mas o menos

+</code>
+Para saber si el cluster de etcd2 esta trabajado correctamente que es la idea de todo esto se puede ejecutar en un nodo algo como:
+etcdctl set /message "Hola"
+y en otro pedir el valor
+etcdctl get /message y deberia devolver Hola
-coreos-install -d /dev/sda -c cloud-config.yaml
