Obviously this doesn't apply 100% to UFS and other=20 filesystems' labels (except if there's a way to identify different file=20 systems by their superblock, for example timestamp of creation?), but in = case of "manual" labels, if the unique ID matches and the label string=20 matches, it's probably the same device. Currently, geom_label discards "additional" devices with the same label, = and I remember there was a discussion about if that should be changed=20 (though I don't remember the conclusions). It would be useful if=20 geom_label would work the same as geom_multipath in this case (i.e.=20 failover to "next" device, add new devices with same label+id to the=20 pool), or even if geom_multipath were merged in geom_label.
