In some cases you may want to deliberately fail the execution of a playbook. In our provisioning workflow we want to have safeguards in place to avoid provisioning systems that are already in production. Since we reboot physical and virtual systems, it is mandatory we take all the precautions to prevent accidental provisioning.

So in our use-case we have the following at the very start of the provisioning playbook:

    ### Safeguard to protect production systems
    - local_action: fail msg="System is not ready to be staged according to CMDB"
      only_if: "'$cmdb_status' != 'to-be-staged'"

and we repeat the same task in the (separate included) play that takes care of (re)booting the system using our own boot-media, so that it cannot be accidentally separately run by someone.

Only gather facts once per node per playbook run

Unless gather_facts: True is on the play

Fix for issue #1194

Make use of UTC dates for RPM timestamp

So they can be shared/compared by people in different timezones

Feature: file info on templates accessible to Jinja2 templates

standardize DOCUMENTATION for nagios, pause

add ansible_managed

attempt at DOCUMENTATION for async_status

Teach fireball mode to disable the fireball by paying attention to 'minutes=N' (default 30) and do not let fireball module crash
on input.

Include a space and a colon after prompts, so you don't have to put them in yourself.  Consistent with documented behavior in examples/playbooks/prompts.yml

Allow non-string types in with_items variables

Add DOCUMENTATION to pause task

Add DOCUMENTATION to nagios module.

Be smarter about when to abort a playbook -- if it's early, we just didn't match any hosts, so keep on, hosts might be dynamic.

Remove debug print statement

Give each task its own module_vars

Otherwise each task will overwrite the previous' items, among
other things.

fireball DOCUMENTATION

- amended

Jumbo DOCUMENTATION patch

Use a regexp to filter out arguments instead

Added missing attribution to all module DOCUMENTATION strings

pipes.quote is a bit overzealous for what we want to do, quoting ;
and other characters that you most likely want to use in your shell
invocations. The regexp is the best I could come up with to be able
to only replace the parts of the arguments that shouldn't be
executed.

If all hosts in a play fail, fail the whole playbook and don't bother printing out every remaining task.

Make sure we retain facts between playbooks
