Use static (persistent) naming instead, /dev/disk/by-label,
/dev/disk/by-id, /dev/disk/by-uuid, and if gpt /dev/disk/by-partlabel
and /dev/disk/by-partuuid

As you found, /dev/sdX bus names are assigned in the order they are
added, which for some time has not been guaranteed to remain
consistent between kernel versions or even subsequent boots on the
same kernel.
