According to 'geom disk list', each of my 22 drives has an "ident", but 
only some of them have "labels".

"ident" is turned into a "label" via a process called "tasting":
   sys/geom/label/g_label_disk_ident.c
   sys/geom/label/g_label.c

Although it is not yet clear to me why apparently only some of my disks 
are "tasted".
