Bug description:
  === Begin SRU Template ===
  [Impact] 
  This is a doc only change.  The related doc is not present in ubuntu
  binary packages.

  [Test Case]
  apt-get source cloud-init
  vi cloud-init*/doc/rtd/topics/datasources/configdrive.rst

  [Regression Potential] 
  None.
     
  [Other Info]
  Upstream commit:
   https://git.launchpad.net/cloud-init/commit/?id=58cc8f7521725d4f00

  === End SRU Template ===

  
  Current documentation states that:
  http://cloudinit.readthedocs.io/en/latest/topics/datasources/configdrive.html#version-2

  ... a config drive: ...Must be a un-partitioned block device
  (/dev/vdb, not /dev/vdb1)...

  This is not correct.

  1. Cloud-init actually, works with ConfigDrive as partition (e.g. /dev/sda1)
  2. Ironic uses partition at the end of disk to write metadata, and it's absurd for baremetal provisioning to dedicate whole disk (actual SATA, SSD, SAS/FC drive) just to tiny metada.
  3. According to @smoser at #cloud-init IRC, " i'm pretty sure the doc is just wrong, ... i'm pretty sure reading current code that if the filesystem has a label of 'config-2', then it will work".

  I think this part of documentation should be rewritten to avoid
  confusion with Ironic workflow for ConfigDrive.
