Здравствуйте!

Из man mdadm:
       --auto-detect
              Request that the kernel starts any auto-detected arrays.  This 
can only work if md is compiled into the kernel — not if it  is a  module.   
Arrays  can  be auto-detected by the kernel if all the components are in 
primary MS-DOS partitions with partition type FD, and all use v0.90 metadata.  
In-kernel autodetect is not recommended for new installations.  Using  mdadm  
to  detect and assemble arrays — possibly in an initrd — is substantially 
more flexible and should be preferred.

То есть, Вы правы, ядро может автоопределять только части массивов, 
находящиеся на дисках с таблицей разделов MS-DOS, на разделе с типом FD и 
метаданными версии 0.90. Остальное автоматически не определится и в массив не 
соберется.

Остается подождать, пока в make-initrd будет реализована поддержка mdadm (в 
планах она есть) - тогда можно будет собирать при загрузке любые типы 
массивов, поддерживаемые mdadm.
