[arch-general] do i need to configure mkinitcpio.conf for my md array ?

Hi i have just configured my 4 disk raid 10 array with mdadm the filesystem is ext4 unencrypted and arch is installed on a separate disk do i need to reconfigure mkinitcpio.conf for my md array so that the array is assembled and started at boot, all the examples i've seen have arch installed on the raid array including the example in the wiki https://wiki.archlinux.org/index.php/RAID i have not reboot the new array yet so i would like to make sure everything necessary is configure before i do that. shadrock
