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.
