Adding /etc/mdadm.conf, with the contents supplied at boot.initrd.mdadmConf.

Browse source 
This allows setting a fixed device name per array, thus ensuring that at boot,
the arrays will always be mounted with the same names. I think this allows
solving the problem of grub getting confused about softraid device names
(prefix and root), if the devices always get the same naming at initrd.
