You're wrong about this.  The boot device is not hardcoded but will
merely be computed at startup time.  That's why you see the message
``Changing root device to ...''.

You're confusing this with the hardcoded idea of wd0 through wd3 which
are mapped to the first/second controller's first/second (possible)
drive, respectively.  Matters are different with SCSI disks, since the
SCSI driver by default assigns the unit numbers dynamically.
