Seems that you - or something - did make the switch from
device names to labels. Maybe your kernel now includes
GEOM functionality for work with labels? But I don't know
of a process that changes /etc/fstab automatically...

You can still use the device names for the /etc/fstab
entries, you just need to make sure that you select
the correct names (as you described above). Then there
should be no problem as labels are optional.
