## Synopsis

- Control running and enabled state for system-wide or user services.
- BSD and Linux systems are supported.

## Requirements

The below requirements are needed on the host that executes this module.

- A system with an active nosh service manager, see Notes for further information.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
enabled boolean | Choices: no yes | Enable or disable the service, independently of `*.preset` file preference or running state. Mutually exclusive with preset. Will take effect prior to state=reset.
name - / required |  | Name of the service to manage.
preset boolean | Choices: no yes | Enable or disable the service according to local preferences in *.preset files. Mutually exclusive with enabled. Only has an effect if set to true. Will take effect prior to state=reset.
state - | Choices: started stopped reset restarted reloaded | `started`/`stopped` are idempotent actions that will not run commands unless necessary. `restarted` will always bounce the service. `reloaded` will send a SIGHUP or start the service. `reset` will start or stop the service according to whether it is enabled or not.
user boolean | Choices: no ← yes | Run system-control talking to the calling user's service manager, rather than the system-wide service manager.

## Notes

Note

- Information on the nosh utilities suite may be found at https://jdebp.eu/Softwares/nosh/.

## Examples

    - name: start dnscache if not running
      nosh: name=dnscache state=started

    - name: stop mpd, if running
      nosh: name=mpd state=stopped

    - name: restart unbound or start it if not already running
      nosh:
        name: unbound
        state: restarted

    - name: reload fail2ban or start it if not already running
      nosh:
        name: fail2ban
        state: reloaded

    - name: disable nsd
      nosh: name=nsd enabled=no

    - name: for package installers, set nginx running state according to local enable settings, preset and reset
      nosh: name=nginx preset=True state=reset

    - name: reboot the host if nosh is the system manager, would need a "wait_for*" task at least, not recommended as-is
      nosh: name=reboot state=started

    - name: using conditionals with the module facts
      tasks:
        - name: obtain information on tinydns service
          nosh: name=tinydns
          register: result

        - name: fail if service not loaded
          fail: msg="The {{ result.name }} service is not loaded"
          when: not result.status

        - name: fail if service is running
          fail: msg="The {{ result.name }} service is running"
          when: result.status and result.status['DaemontoolsEncoreState'] == "running"
