Hi,

If I for example I would like to run some cmds after init. I can use the
runcmd tag.

runcmd:
  - echo "Hello, I run on first boot"
  - /usr/local/bin/setup.sh

However, this only works if in the cloud.cfg file in the image contains
something like the following

cloud_final_modules:
 - [runcmd, always]

If not the runcmd is simply ignored, and no warning message is given. It
is not directly clear from the manual that this must be present, and no
warning is given, which made me wonder why it was not working.


Met vriendelijke groeten,

Thanks for making cloud-init better. What do you mean by config tags?
Could provide an example of your use case and what is the expected
behavior? Thanks.

Title:
  no warning message when using tags that are not present/enabled in the
  cloud.cfg file

Status in cloud-init package in Ubuntu:
  New

Bug description:
  It is not perse a bug, but more a documentation/logging issue. I had
  trouble to get my instance configured trough cloud init, because the
  config tags i tried to use where not present/enabled in the cloud.cfg
  file of the image i was using. Documentation explains the tags, but it
  took some time to realize that they also need be enabled in the
  cloud.cfg file. I had for example the network: tag, but nothing was
  configured, because the tag was not enabled in the cloud.cfg in the
  image I was using. I would be nice, to get a warning message in the
  log that a given tag is ignored, because the tag is not enabled in the
  cloud.cfg file of the image.
