} A wedge only has a single name. Wedges are automatically configured from
} a GPT, a wedge names is taken from the partition label or if that
} isn't that or already exists, from the partition GUID. If the GUID
} also conflicts, the wedge isn't configured.

     Personally, I would consider this to be a serious flaw.  For
entities that have a GUID/UUID it should always be possible to
refer to them that way.  However, I see that struct dkwedge_info
doesn't have a seperate field for that.  Perhaps this is something
that should be considered.
