Comment # 4 on bug 1094963 from Stefan Hundhammer

From 01-probed.xml:

    <Luks>
      <sid>48</sid>
      <name>/dev/mapper/cr-auto-1</name>
      <sysfs-name>dm-0</sysfs-name>
      <sysfs-path>/devices/virtual/block/dm-0</sysfs-path>
      <region>
        <length>34236416</length>
        <block-size>512</block-size>
      </region>
      <dm-table-name>cr-auto-1</dm-table-name>
      <mount-by>device</mount-by>
      <in-etc-crypttab>false</in-etc-crypttab>
      <uuid>d01e6a0c-46c1-4ce0-8f30-103984bc2d6f</uuid>
    </Luks>


So it appears that this LUKS was not in /etc/crypttab (?); not sure if this
contributed to the problem.
