No puedo arrancar sin un initrd

Quiero iniciar mi sistema sin initrd y compilé un kernel personalizado. Agregué todo lo que necesitaba (sistemas de archivos, controladores de dispositivos, etc.) y no son módulos. Pero cuando intento arrancar sin initrd/initramfs dice: no se puede abrir el dispositivo raíz o el bloque desconocido (0 0) sin initramfs. ¿Como puedo resolver esto? Mensaje de error

Parece que tienes un /dev/md0 como dispositivo raíz.

Para que su SW RAID se ensamble automáticamente durante el arranque, necesita:

  1. Estar en una partición de tipo FD (Linux Raid).
  2. Para tener un superbloque más antiguo (creado con --metadata=0.90un parámetro agregado a su archivo mdadm --create.
