Your system uses MBR, hence the ad0s prefix.
UFS labels can be set while in singleuser mode, this is particular
important for the root filesystem.
1. Reboot to singleuser mode.
2. Hit the enter key when asked about which shell to launch.
3. tunefs -L root /dev/ad0s1a
4. Ditto for the other *UFS* partitions. Consult your /etc/fstab.
5. Verify the labels using dumpfs /dev/ad0s1a
6. Reboot to multiuser mode.
7. Duplicate the necessary lines in /etc/fstab.
8. Comment out the original lines, in case you must revert.
9. Change the duplicate lines to refer to /dev/ufs/root, etc.
10. Reboot to see if you have succeeded.
11. Remove the original lines in /etc/fstab, if desired.
I recall issues in the past using glabel(8) which stores the label in
the last disk block (sector) of the partition. Hence the labeled
device file should present a device which is one disk block shorter to
avoid the label being overwritten. Maybe someone else can chime in on
I prefer GPT labels. See gpart(8), in particular
gpart modify -l label -i index diskdevice.
