The local drives won't move around on you. They're not subjected to the
same dynamic mapping that's incurred when you use remote disks. But if
you're worried about it, you could mount by label. Just use `xfs_admin
-L my_data_disk /dev/sdb1` to label the partition and use
LABEL=my_data_disk in place of /dev/sdb1 your fstab.
