It means that someone should update this driver. But unless you are using your
parallel port for IP traffic (and who does these days?) it won't bother you.

The geom software now automatically assigns (unchanging) labels to UFS
filesystems. This enables people to mount filesystems correctly even if the
harddisk is moved to a different controller. E.g. /dev/da4s1g might become
/dev/da6s1g, but its labeled device /dev/ufsid/482e0880cf225c60 would not
change. The labels are removed if a partition is mounted, which the warning
mentions. It is harmless.

You might have to dig into the geom code... :-)
