You cannot control the order. Period. It is pseudo-random based on
hardware responses to driver loads. New kernels can have entirely
different orders of devices, and if parallel loads are allowed, you can
have one controller get sd[aceg] while another gets sd[bdfh]. The entire
system of LABEL= and UUID= support via initramfs and blkid is intended
make fstab and other utilities deterministic in spite of varying names.
mdadm has always been resistant to naming problems thanks to its device
#s and UUIDs in the superblocks.
