Title:
  cloud-init-single-module-fails-to-merge

Status in cloud-init:
  Expired

Bug description:
  I have a yaml file in a local directory (cloud-init.yaml) which
  contains 2 modules (write_files, runcmd). I am exercising the
  write_files module using the following command:

  $ sudo cloud-init --debug --file cloud-init.yaml single --name
  cc_write_files

  From the debug output I can see that the local file
  (/home/mmorais/cloud-init.yaml) is not getting merged into the master
  config file (/var/lib/cloud/instance/cloud-config.txt).

  2014-05-05 21:25:45,371 - util.py[DEBUG]: load_yaml given empty string, returning default

  As a workaround I am copying /home/mmorais/cloud-init.yaml to
  /var/lib/cloud/instance/cloud-config.txt which defeats the purpose of
  being able to run cloud-init on arbitrary files for testing.

  Also note that the command above does not work at all unless I specify
  *cc_write_files* instead of *write_files*.

  I am running cloud-init (0.7.4).
