Assign each UFS filesystem a label with fstab -L.  Have fstab reference
this label and not the device/partition name.

Configure a gmirror into the swap area and then reference this in fstab
(a gmirror may be created with only one member).

These will then work no matter which ATA/AHCI/SIIS/SAS driver is used as
GEOM will find them and set up the names for fstab to use.
