aa30608b44 Modify device numbering method to work with latest -CURRENT. Briefly,
the device numbers are now minor number only, so that we can still
compare them after dev_t has turned into a blob.

240b9c4449 Describe the new semantics of 'create':
When creating a new drive, if the drive already has a vinum label,

  'force' flag is specified.

Update information about partition type for Vinum drives.  They
*should* be of type 'vinum', but currently we still accept (and
complain about) partitions of type 'unused'.  At a later date, only
'vinum' will be accepted.
