Glabel is a "read-only" tool (i.e. it only reads existing labels) in
all but one case: it can create a special type of labels not related
to file systems. It has nothing to do with "tunefs -L".

But is that your original problem? If you have all three labels
pointing to the same file system (glabel, UFS volume label, UFS ID
label), you actually have 4 /dev entries pointing to the same device?
