Hmmm.  Is there stuff written on the disk.  Is root stuff really written
on da0s1d and /home stuff really written on da0s1a?   Does the system boot 
from it OK?   

Or is it just that the mounts are switched.   
The mount points are not written in to the label.   That comes after
booting.   If it boots, I wonder if it really is switched on the
partitions or if it is just that the partitions are mounted backwards
(probably due to editing /etc/fstab incorrectly).
