This is fixed AFAICT

FWIW, the comment in the code at mapped-devices.scm ...

  (source    mapped-device-source)                ;string

... is not current with the doc, which says ...

     ‘source’
          This is either a string specifying the name of the block
          device to be mapped, such as ‘"/dev/sda3"’, or a list of such
          strings when several devices need to be assembled for creating
          a new one.
